Operational efficiency and the growth of short-term memory span

Four studies are reported which link developmental increases in memory span with developmental increases in operational speed or efficiency. In the first, a linear relationship is demonstrated between increases in word span and increases in speed of word repetition. In the second, adults and 6-year-olds are equated on speed of word repetition, by manipulating word familiarity. It is shown that their word spans are no longer different under these conditions. Similar findings are then reported for a test of M space called “Counting Span.” First, a linear relationship is demonstrated between increases in Counting Span and increases in speed of counting. Next, adults and 6-year-olds are equated on speed of counting, by forcing adults to count in an unfamiliar language. It is shown that their counting spans are no longer different under these conditions. The conclusion is that developmental increases in memory span do not result from increases in total processing space. Rather, with development, basic operations become faster and more efficient. This means that they require less processing space, and that more space becomes available for storage as a result.     

Semantic interpretation effects on memory for faces

Five experiments investigated the effects of semantically interpreting faces on their recognition. Experiment 1 demonstrated that faces could meaningfully be related to occupational categories. In Experiments 2–5, each of a set of faces was presented with either the label of a congruent occupational category or a noncongruent label. Presenting a face with a congruent occupational label was found to enhance recognition that the face had previously been seen (Experiments 2–4), but congruent labeling also impaired the detection of distractor faces that matched previously seen faces’ categories (Experiments 3 and 4). In a forced-choice recognition test, in which distractors were highly similar to originally seen faces, congruent occupational labeling failed to increase recognition of previously seen faces (Experiment 5). These results indicate that interpreting faces, with respect to stereotyped categories, ratherthan improving a physical codein memory, led to theformation of a semantic code, which increased recognition of old items at the expense of the detection of new items. Another general finding was that faces that were rated more stereotypical were more recognizable, regardless of the accompanying label.     

Sex-role attitudes: Who should raise consciousness?

Attitudes of teachers and counselors-in-training toward women's roles, sex-role identity, and tolerance for gender-role norm violators were examined following a semistructured consciousness-raising group. Significant differences were found between the two treatment groups on the Attitudes Towards Women Scale. The results are discussed in terms of social reinforcement of a feminist model as instructor. The study casts doubt on the generalizability of traditional attitudes among helping professionals and raises the practical question of who should teach courses and workshops in sex-fair counseling.     

When is it wrong to eat animals? The relevance of different animal traits and behaviours

Research suggests that animals’ capacity for agency, experience, and benevolence predict beliefs about their moral treatment. Four studies built on this work by examining how fine‐grained information about animals’ traits and behaviours (e.g., can store food for later vs. can use tools) shifted moral beliefs about eating and harming animals. The information that most strongly affected moral beliefs was related to secondary emotions (e.g., can feel love), morality (e.g., will share food with others), empathy (e.g., can feel others' pain), social connections (e.g., will look for deceased family members), and moral patiency (e.g., can feel pain). In addition, information affected moral judgements in line with how it affected superordinate representations about animals’ capacity for experience/feeling but not agency/thinking. The results provide a fine‐grained outline of how, and why, information about animals’ traits and behaviours informs moral judgements.     

The world may not be just for you but you'd better not say it: On the social value of expressing personal belief in a just world

The expression of personal belief in a just world (PBJW) has been discussed as a criterion of excellence in social judgments. In four experimental studies we hypothesized and found that targets who express high versus low PBJW are judged as more: (i) deserving of success and (ii) suited to socio-organizational expectations. The four studies show that suitability to socio-organizational expectations mediates the relation between PBJW expressed and success deservingness, even after controlling for judgments of likability, status, rationality, optimism, and targets as victims. Studies 2 and 3 show this pattern occurs regardless of target performance appraisal. Study 4 indicates that expressing low PBJW decreases the social value of individuals, but expressing high PBJW does not increase it. We discuss the impact of PBJW expression on people's lives, namely on upward social mobility of members of low-status groups, and the influence of the negativity bias on judgments caused by PBJW expression.     

Understanding Conspiracy Theories

Scholarly efforts to understand conspiracy theories have grown significantly in recent years, and there is now a broad and interdisciplinary literature. In reviewing this body of work, we ask three specific questions. First, what factors are associated with conspiracy beliefs? Our review of the literature shows that conspiracy beliefs result from a range of psychological, political, and social factors. Next, how are conspiracy theories communicated? Here, we explain how conspiracy theories are shared among individuals and spread through traditional and social media platforms. Next, what are the societal risks and rewards associated with conspiracy theories? By focusing on politics and science, we argue that conspiracy theories do more harm than good. We conclude by suggesting several promising avenues for future research.     

Memory: Between traumatic shock and psychic historicization

‘I want to erase him from my memory,’ she said, ‘his eyes, his eyes staring at me … they are there every night, his hand … every night it hits me again and again …’. On the basis of these few words taken from the therapeutic work with Keltoum, the author reflects theoretically and clinically on the place of memory in a traumatism: a fixed memory, a ‘frozen image’, the signs of a traumatic compulsion to repeat, are the expressions of a process of psychic disorganization but also of a ‘symbolized and symbolizing’ memory anticipating a possible historicization of this memory, of a path, therefore, towards a resolution of the trauma resulting from a process of psychic integration and reorganization.
