Object recognition and object segregation in infancy: historical perspective, theoretical significance, "kinds" of knowledge, and relation to object categorization

Needham (2001, this issue) reports that 4.5-month-old infants can use a short-term familiarization experience with a single object to facilitate the segregation of a visual display consisting of a configurally similar object and a configurally dissimilar adjacent object. We reflect on this finding in the larger context of Needham's systematic research on the development of object perception, a program that has included (1) a series of empirical studies designed to identify the different cues that infants use for object segregation and (2) a theoretical framework in which infants are presumed to integrate these cues to form interpretations of complex visual displays.     

Affective disgust predicts blame for gay male homicide victims

For certain crimes there is a tendency in the United States to blame individuals for their victimization. Previous work has shown that affective states can impact blame attribution. Drawing upon this work, the purpose of the current pre-registered research was to examine the relation between affective disgust and victim blame attribution. In Study 1, as participants’ (N = 203) level of implicit disgust associations with gay men increased, their tendency to blame a gay male homicide victim also increased, whereas their agreement that the homicide qualified as a hate crime decreased. In Study 2, disgust was experimentally induced by exposing participants (N = 431) to disgusting (e.g., vomit, insects) or neutral images (e.g., mug, stapler). Inducing disgust increased victim blame and decreased perceptions that the homicide constituted a hate crime. However, exploratory mediation analyses in both studies showed that the impact of disgust on hate crime applications is best explained as an indirect effect of victim blame. Taken together, these findings suggest that both individual differences in implicit gay-disgust and situational feelings of disgust may underlie people’s perceptions of how blameworthy a victim is for the crime committed against them.     

Gender and Country Differences in Alcohol-Aggression Expectancy and Alcohol-Related Intimate Partner Violence

Drinking is associated with a higher rate of violent offending among males and a higher rate of violent victimization among females. Using comparable self-reported data, this study examines between the United States (n = 2,363) and Japan (n = 1,660) whether the gender difference in alcohol-related Intimate Partner Violence (IPV) is explained by alcohol-aggression expectancy. The results indicate that though males are more likely than females to expect that alcohol would make them more aggressive, alcohol-aggression expectancy cannot explain the gender difference in alcohol-related IPV. In both countries, instead, alcohol use of males most strongly accounted for the gender difference in alcohol-related IPV.     

Development of the other-race effect during infancy: Evidence toward universality?

The other-race effect in face processing develops within the first year of life in Caucasian infants. It is currently unknown whether the developmental trajectory observed in Caucasian infants can be extended to other cultures. This is an important issue to investigate because recent findings from cross-cultural psychology have suggested that individuals from Eastern and Western backgrounds tend to perceive the world in fundamentally different ways. To this end, the current study investigated 3-, 6-, and 9-month-old Chinese infants’ ability to discriminate faces within their own racial group and within two other racial groups (African and Caucasian). The 3-month-olds demonstrated recognition in all conditions, whereas the 6-month-olds recognized Chinese faces and displayed marginal recognition for Caucasian faces but did not recognize African faces. The 9-month-olds’ recognition was limited to Chinese faces. This pattern of development is consistent with the perceptual narrowing hypothesis that our perceptual systems are shaped by experience to be optimally sensitive to stimuli most commonly encountered in one’s unique cultural environment.     

The role of facial orientation in newborn infants’ preference for attractive faces

Several previous experiments have found that newborn and young infants will spend more time looking at attractive faces when these are shown paired with faces judged by adults to be unattractive. Two experimental conditions are described whose aim was to find whether the ‘attractiveness effect’ is affected by the orientation of the facial stimuli. Pairs of attractive and less attractive faces (as judged by adults) were shown to newborn infants (mean age 2 days 20.5 hours), where each pair was presented both upright and inverted through 180°. In the former (upright) condition, but not the latter (inverted) condition, the infants looked longer at the attractive faces, and the difference in attractiveness preference between the conditions was statistically significant. These findings are clear evidence that infants’ early representation of faces contains information about faces that is orientation‐specific. The results are discussed in terms of innate facial representations and rapid learning about faces in the hours from birth.     

Development and Validation of the Short Grit Scale (Grit–S)

Two experiments investigated the possibility that external statements in the Rotter I-E scale are more depressing in tone than internal statements, and thus depressed subjects may respond to external items due to item mood level rather than locus of control content. Results of Experiment 1 revealed that the external alternative was rated as more depressing than its internal counterpart for the majority Of the 23 I-E items (18 for females and 15 for males), while a small number of I-E items (3 for females and 6 for males) contained internal and external statements rated as balanced for depressing Content. For two I-E items the internal alternative was rated as more depressing. Results of Experiment 2 revealed that endorsement of external items was significantly related to self-reported depression for both total I-E score and for the item subset where external statements(as revealed in Experiment 1) were the more depressing of the item pair. External endorsement was not significantly related to depression for the I-E item subset where options are balanced for mood level, while endorsement of internal statements was related to depression only for the item subset where the internal option was rated as more depressing. These results were interpreted as supporting prior research which demonstrated mood response set using altered Rotter I-E scale items, Implications for use of the Rotter I-E scale in the study of depression were discussed.
