The current research examined the proposition that debates over same-sex marriage are characterized, at least in part, by conflicting understandings about what is and is not prejudiced, normative and true. Toward this end, Australians' (N = 415) prejudice judgements of supportive and oppositional statements toward same-sex marriage were measured and analysed with analyses of variance. Unsurprisingly, same-sex marriage supporters perceived a supportive statement as unprejudiced, tolerant, truthful, in pursuit of individual liberty, and normative; oppositional statements were seen in precisely the opposite manner. Same-sex marriage opponents, however, disagreed, instead judging an oppositional statement as unprejudiced, tolerant, truthful, in pursuit of individual liberty, and normative; it was a supportive statement that was seen as relatively prejudiced. These effects remained even after controlling for independent expressions of in-group favouritism. The current data align with a collective naïve realism perspective, in which group members see their own views as veridical and those of disagreeing others as biased. We argue that prejudice-reduction efforts must be instantiated to facilitate a common in-group identity between supporters and opponents to enable consensus over facts and, ultimately, what is and is not prejudice. Without this consensus, each side of the political debate may simply hurl the pejorative label of "prejudice" against the other, with likely little opportunity for social influence and social change.

Objective magnitude representations may be prone to subjective percepts when judging human beings. An elderly man is clearly "large" in terms of age. But, is he truly perceived as "big" in our minds? We investigated whether "objective" representation of age interacts with subjective stereotypical percepts of aging, using a numeral classification task preceded by prime images containing human figures. First, prime images of children and young adults demonstrated a positive correlation between perceived age and numerical size. Second, negatively and positively valenced prime images were associated with small and big numerical values, respectively. Third, joint effects of age and valence on numerical value perception revealed a linkage between old adults and small numerical values. It seems that magnitude perception is vulnerable to implicit subjective biases and stereotypical judgments dominate objective magnitude representation.

A recently published test of face perception, the Oxford Face Matching Test, asks participants to make two judgements: whether two faces are of the same individual and how perceptually similar the two faces are. In this study, we sought to determine to what extent the test can be shortened by removing the perceptual similarity judgements and whether this affects test performance. In Experiment 1, participants completed two versions of the test, with and without similarity judgements, in separate sessions in counterbalanced order. The version without similarity judgements took approximately 40% less time to complete. Performance on the matching judgements did not differ across versions and the correlation in accuracy across the two versions was comparable with the originally reported test-retest reliability value. Experiment 2 validated the version without similarity judgements against other measures, demonstrating moderate relationships with other face matching, memory, and self-report face perception measures. These data indicate that a test version without the similarity judgements can substantially reduce administration time without affecting test performance.

Review
We organize image types by their substantive relationship with textual claims and discuss their impact on attention, comprehension, memory, and judgment. Photos do not need to be false (altered or generated) to mislead; real photos can create a slanted representation or be repurposed from different events. Even semantically related non-probative photos, merely inserted to attract eyeballs, can increase message acceptance through increased fluency. Messages with images receive more attention and reach a wider audience. Text-congruent images can scaffold the comprehension of true and false claims and support the formation of correct and false memories. Standard laboratory procedures may underestimate the impact of images in natural media contexts: by drawing all participants' attention to a message that may be ignored without an image, they inflate message effects in the control condition. Misleading images are difficult to identify and their influence often remains outside of awareness, making it hard to curb their influence through critical-thinking interventions. Current concerns about deep fakes may reduce trust in all images, potentially limiting their power to mislead as well as inform. More research is needed to understand how knowing that an image is misleading influences inferences, impressions, and judgments beyond immediate assessments of the image's credibility.

The sense of agency is the ability to recognize that we are the actors of our actions and their consequences. We explored whether and how spatial cues may modulate the agency experience by manipulating the ecological validity of the experimental setup (real-space or computer-based setup) and the distance of the action-outcome (near or far). We tested 58 healthy adults collecting explicit agency judgments and the perceived time interval between movements and outcomes (to quantify the intentional binding phenomenon, an implicit index of agency). Participants show greater implicit agency for voluntary actions when there is a temporal and spatial action-outcome contingency. Conversely, participants reported similar explicit agency for outcomes appearing in the near and far space. Notably, these effects were independent of the ecological validity of the setting. These results suggest that spatial proximity, realistic or illusory, is essential for feeling implicitly responsible for the consequences of our actions.

In order to investigate whether handwriting has an advantage in learning word form, sound, and meaning, this study randomly selected 40 elementary school student participants (20 males, 20 females, aged 11.4 ± 1.34 years). Using an experimental approach, we compared the learning outcomes of word sound matching, word meaning matching, and word form judgment tasks under two conditions: handwriting and visual learning. After three consecutive days of learning and testing, we found that handwriting generally outperformed visual learning in terms of accuracy and response time in word form, sound, and meaning learning. Additionally, we observed differences in the timing of significant discrepancies in learning outcomes between the two methods across the three tasks. Specifically, in terms of accuracy, discrepancies first appeared in the word sound matching task on the first day, followed by the word form judgment task, and lastly the word meaning matching task. Regarding response time, significant differences between learning methods first emerged in the word form judgment task, followed by the word sound and word meaning tasks. Thus, combining accuracy and response time data, we conclude that handwriting is more advantageous than visual learning for word acquisition, with a differential impact on word form, sound, and meaning, where word form and sound are prioritized over meaning.

Across four experiments, we investigate the mechanism that underlies the elongation bias. We find individuals tasked with assessing the area of two objects do so by comparing the objects' dimensions, and thus subtle changes in the objects' dimensions can impact area assessments. Because a typical elongation bias experiment places two objects side-by-side horizontally and varies the elongation ratio while maintaining the same area, height is generally easier to compare than width. Thus, there will exist a region where the change in height noticeably crosses a perceptual just noticeable difference boundary, but the corresponding change in width does not, and individuals will tend to perceive that the taller object has a greater area or volume. Consistent with this proposed process, we suggest that, although the elongation bias occurs under a comparative judgment, it does not do so under a single judgment situation. This research contributes to our wider understanding of the visual processes underlying area comparisons.

Serial dependence (SD) refers to the effect in which a person's current perceptual judgment is attracted toward recent stimulus history. Perceptual and memory processes, as well as response and decisional biases, are thought to contribute to SD effects. The current study examined the processing stages of SD facial identity effects in the context of task-related decision processes and how such effects may differ from visual working memory (VWM) interactions. In two experiments, participants were shown a series of two sequentially presented face images. In Experiment 1, the two faces were separated by an interstimulus interval (ISI) of 1, 3, 6, or 10 s, and participants were instructed to reproduce the second face after a varying response delay of 0, 1, 3, 6, or 10 s. Results showed that SD effects occurred most consistently at ISI of 1 s and response delays of 1 and 6 s consistent with early and late stages of processing. In Experiment 2, the ISI was held constant at 1 s, and to separate SD from VWM interactions participants were post-cued to reproduce either the first or the second face. When the second face was the target, SD effects again occurred at response delays of 1 and 6 s, but not when the first face was the target. Together, the results demonstrates that SD facial identity effects occur independently of task-related processes in a distinct temporal fashion and suggest that SD and VWM interactions may rely on separate underlying mechanisms.

The practice of keeping dairy cows with their calves continues to gain interest. Cow-calf contact, or lack thereof, is expected to affect emotional states, but this requires empirical testing. Different types of cow-calf contact may also affect the emotional states of cows. The primary objective of this study was to assess the emotional state of dairy cows with full-time (23 h/d), part-time (10 h/d), or no-contact with their calves (separated 48 h after birth), using a visual judgment bias test (JBT) about one month after calving; JBT is the current gold-standard method to assess emotional state in animals by evaluating optimism or pessimism (illustrated by the proverbial half-full or half-empty water glass). The secondary objective was to compare outcomes of color- versus shape-based visual JBT. Fifty dairy cows were trained to approach a positive image on a screen (rewarded with food) and to avoid a negative image (else punished with waving bag). Once learned (>80% correct over 2 consecutive days), cows were presented with 3 ambiguous images (each presented once per day among 4 positive and 3 negative images, repeated over 4 d), and their approach responses recorded. For the color method (10 full-time, 9 part-time and 11 no-contact cows), positive and negative images were a solid red or white background; ambiguous images were shades of pink. For the shape method (8 full-time, 6 part-time and 6 no-contact cows), positive and negative images were a white circle or cross on a black background; ambiguous images were overlaid circle and cross in varying shades of gray. Cows learned to discriminate colors quicker than shapes (7.3 d, confidence limits [CL]: 6.6-8.2 d; vs. 9.3 d, CL: 8.1-10.6 d). Approaches to ambiguous colors followed a generalization curve (81.0, 33.1, and 5.0 ± 3.7% for near-positive, middle, and near-negative images, respectively), but not approaches to ambiguous shapes (31.9%, 25.7%, and 21.9% ± 4.8%, respectively), indicating colors over shapes should be used in visual JBT for cattle. Part-time cows approached fewer ambiguous color images than full-time cows (23.5%, CL: 13.4%-34.4%; vs. 44.8%, CL; 32.8%-57.1%) whereas no-contact cows were intermediate, but not different from full-time or part-time cows (37.8%, CL; 26.8%-49.5%). The color JBT results show a pessimistic bias (indicating a negative emotional state) in cows with part-time calf contact, possibly due to repeated daily separation from her young calf, relative to cows with full-time calf contact. Thus, cow-calf contact systems appear to influence the emotional state of cows depending on the practice. Cows without calf contact showed no difference in judgment bias between cows with full- or part-time calf contact, suggesting these cows probably do not experience a pervasive negative emotional state (relative to those with calf contact) approximately 30 d after calf separation. However, individual variability in judgment bias was evident for all treatments. The visual judgment bias test is a useful methodology for assessing emotional states of dairy cows; future research should prioritize understanding the emotional states of dairy cows in alternative management systems.

The manuscript is a critical commentary on the article 'Does blame always shift? Examining the impact of workplace safety communication language on post-accident blame attributions for multiple entities'. In this commentary, I find that the reasoning provided for the non-shifting of blame across entities in the causal chain is not adequate. I use a zero-sum game analogy for blame attributions to provide evidence for this inadequacy. In this commentary, I further point out that the focal article does not account for the similarities and dissimilarities between the people making the attributions and the people against whom attributions are being made.
