Individual differences in delay discounting: relation to intelligence, working memory, and anterior prefrontal cortex

Lower delay discounting (better self-control) is linked to higher intelligence, but the basis of this relation is uncertain. To investigate the potential role of working memory (WM) processes, we assessed delay discounting, intelligence (g), WM (span tasks, 3-back task), and WM-related neural activity (using functional magnetic resonance imaging) in 103 healthy adults. Delay discounting was negatively correlated with g and WM. WM explained no variance in delay discounting beyond that explained by g, which suggests that processes through which WM relates to delay discounting are shared by g. WM-related neural activity in left anterior prefrontal cortex (Brodmann's area 10) covaried with g, r= .26, and delay discounting, r=-.40, and partially mediated the relation between g and delay discounting. Overall, the results suggest that delay discounting is associated with intelligence in part because of processes instantiated in anterior prefrontal cortex, a region known to support the integration of diverse information.     

The interactive effects of job advertisement characteristics and applicant experience on reactions to recruitment messages

Job seekers often use job advertisements presented during the early stages of recruitment to gather important information about potential employers. Content of these advertisements as well as associated peripheral cues have the potential to influence job seekers' organizational attitudes. Using the elaboration likelihood model as a theoretical framework, the authors proposed that job seekers' previous work and job search experience moderate the extent to which these job advertisement characteristics influence attitudes towards organizations. Results suggest that the content of job advertisements influence the organizational attitudes of experienced job seekers more than their inexperienced counterparts. Additionally, the presence of peripheral cues (i.e. physical attractiveness of those persons shown in recruitment material) appears to have a greater effect on the organizational attractiveness perceptions of job seekers having less work and job search experience versus those having more experience. Implications of the findings regarding organizational recruitment practices are discussed.     

Social class background and the school-to-work transition

Whereas in years past, young people typically made a discrete transition from school to work, two ideal typical routes now characterize the sharing of school and work roles during adolescence and the transition to adulthood. Longitudinal data from the Youth Development Study show that one route involves less intensive employment during high school, followed by continued part-time employment and postsecondary educational investment. This pathway, more common for youth of higher-class origins, is especially beneficial for young people from lower socioeconomic backgrounds. A second route is early intensive work experience during high school that is less conducive to longer-term educational and wage attainments.     

Analytical psychology and Daoist inner alchemy: a response to C.G. Jung's 'Commentary on The Secret of the Golden Flower'

Abstract :  This paper provides a historical, religious-philosophical context for the study of the Daoist text known as  The Secret of the Golden Flower . An updated study is conducted into the controversy over the source of the text including the editions translated by Richard Wilhelm and Thomas Cleary. The main teachings of the text and the basics of two major denominations of Daoism are introduced to ground later critiques of Jung's commentary. The psychodynamics of analytical psychology, especially those concerned with integration of unconscious contents and the realization of the self (individuation) are compared with the psycho-spiritual dynamics of integration in Eastern spirituality based on the Golden Flower text. The paper concludes that it was amiss for Jung to have equated the Western 'unconscious' with states of higher consciousness in Eastern meditation practices, although his claim that Eastern higher consciousness is characterized by a nebulous state of non-intentionality does raise questions about the appropriateness of calling Eastern meditative states 'consciousness'. A new concept is required to characterize the special qualities of this psychic state shared generally by Eastern spiritual traditions and a more meaningful comparison may be found in Jung's concept of the self.     

Childhood IQ and in-service mortality in Scottish Army personnel during World War II

The Scottish Mental Survey of 1932 (SMS1932) provides a record of intelligence test scores for almost a complete year-of-birth group of children born in 1921. By linking UK Army personnel records, the Scottish National War Memorial data, and the SMS1932 dataset it was possible to examine the effect of childhood intelligence scores on wartime military service mortality in males. There were 491 matches between World War II (WWII) Scottish Army fatalities and the SMS1932 database; 470 (96%) had an age 11 mental ability score recorded. The mean (S.D.) age 11 IQ score of those who died on active service in WWII was 100.78 (15.56), compared with 97.42 (14.87) for male Army survivors (p < 0.0001; Cohen's d = 0.22). Men who took part in the SMS1932 and who were not found in the Army database had a higher mean score (100.45, S.D. =14.97) than those men who had been in the Army, regardless of whether they died or survived (mean IQ = 97.66, S.D. = 14.94; p < 0.0001; Cohen's d = 0.19). Male soldiers with a higher childhood IQ had a slightly increased risk of dying during active service in WWII. Men who did not join the Army had a higher IQ than men who did. Further research in this area should consider naval and air force personnel records in order to examine more fully the complex relationship between IQ and survival expectancy during active service in WWII.     

Explaining Gender Differences in Depression: an Interpersonal Contingent Self-Esteem Perspective

The quality of interpersonal relationships may be a key factor in the etiology of depression. An interpersonal depressive vulnerability has been proposed to interact with interpersonal stressors to predict depressive symptoms. Research examining gender differences in this link has been inconclusive. We propose that research should focus on whether one’s self-esteem is based on the quality of interpersonal relationships. We propose a model of gender differences in depression that examines the role of interpersonal contingent self-esteem (ICSE) in the development of depression. Specifically, we propose that ICSE interacts with gender in the face of interpersonal stress to promote decreases in momentary self-esteem. Decreases in momentary self-esteem, in turn, lead to rumination, maladaptive interpersonal behaviors, and depressive symptoms.     

Parental Engagement and Barriers to Participation in a Community-Based Preventive Intervention

This study examined parent characteristics and barriers to participation in a community-based preventive intervention with a sample of 201 parents from low-income and predominantly ethnic minority backgrounds. Person-centered analyses revealed five subgroups of parents who demonstrated variability in their parent characteristics, which included psychological resources and level of parental involvement in education. Group membership was associated with differences in school involvement and use of the psychoeducational intervention at home, after accounting for the number of barriers to engagement. For the intervention attendance variable, greater number of barriers was associated with decreased attendance only for parents in the resilient subgroup and the psychologically distressed subgroup. Attendance remained constant across levels of barriers for the other three subgroups of parents. The results of the study inform theory and practice regarding how to tailor preventive interventions to accommodate subgroups of parents within populations that experience barriers to accessing mental health services.     

Further Development of the Interpersonal Contingencies Model: Our Reply to the Mezulis & Funasaki and Burwell & Shirk Commentaries

In our reply to the commentaries on Cambron, Acitelli, & Pettit’s paper (this issue), we address the issue discussed in both commentaries: the need to take a developmental approach to the study of gender differences in depression. In response to Mezulis and Funasaki (this issue), we attempt to specify where the Cambron et al. paper supports their point that vulnerability, stress, and vulnerability-stress interaction may vary across domains. We also enumerate several hypotheses that are derived from our model of gender differences in depression. In response to Burwell and Shirk (this issue), we agree with the need to investigate the origin of self-esteem contingencies, and that the measurement of self-esteem contingencies is fraught with problems. We also remind readers that whether examining interpersonal relationship or physical appearance risk factors for depression, we must focus on the extent to which one’s self-esteem is based on that domain.     

Religion and Support for Suicide Attacks

ABSTRACT— In four studies carried out across different cultural, religious, and political contexts, we investigated the association between religion and popular support for suicide attacks. In two surveys of Palestinians and one cognitive priming experiment with Israeli settlers, prayer to God, an index of religious devotion, was unrelated to support for suicide attacks. Instead, attendance at religious services, thought to enhance coalitional commitment, positively predicted support for suicide attacks. In a survey of six religions in six nations, regular attendance at religious services positively predicted a combination of willing martyrdom and out-group hostility, but regular prayer did not. Implications for understanding the role of religion in suicide attacks are discussed.     

Why is visual search superior in autism spectrum disorder?

This study investigated the possibility that enhanced memory for rejected distractor locations underlies the superior visual search skills exhibited by individuals with autism spectrum disorder (ASD). We compared the performance of 21 children with ASD and 21 age‐ and IQ‐matched typically developing (TD) children in a standard static search task and a dynamic search task, in which targets and distractors randomly changed locations every 500 ms, precluding the use of memory in search. Children with ASD exhibited overall faster reaction time (RT) relative to TD children, and showed no disruption in search efficiency in the dynamic condition, discounting the possibility that memory for rejected distractors augments their visual search abilities. Analyses of RT x set size functions showed no group differences in slopes but lower intercepts for the ASD group in both static and dynamic search, suggesting that the ASD advantage derived from non‐search processes, such as an enhanced ability to discriminate between targets and distractors at the locus of attention. Eye‐movement analyses revealed that the ASD and TD groups were similar in the number and spatial distribution of fixations across the search array, but that fixation duration was significantly shorter among children with ASD. Lower intercepts in static search were related to increased symptom severity in children with ASD. In summary, ASD search superiority did not derive from differences in the manner in which individuals with ASD deployed their attention while searching, but from anomalously enhanced perception of stimulus features, which was in turn positively associated with autism symptom severity.
