The psychological costs of knowledge specialization in groups: Unique expertise leaves you out of the loop

Knowledge specialization, such as that present in cross-functional teams, produces both positive and negative outcomes. Our research investigated how unique expertise can lead to feelings of ostracism in the form of being out of the loop. Compared to group members with shared expertise, members with unique expertise felt out of the loop and experienced decreased fulfillment of fundamental needs, particularly when their expertise was to be given less weight in the group’s decision. Possessing unique expertise did not inhibit leadership emergence, even when that expertise should not have been used in the decision-making process. So, although knowledge specialization can have positive consequences for teams and task performance, it also has some negative psychological consequences that need to be understood.     

Portrait of a creatively gifted child facing cancer

Creativity can be demonstrated in various ways. The following case study describes how one creatively gifted boy applied creative skills from one dimension of his life to a totally new one. When cancer halted his musical career, he chose to channel his abilities into a new challenge: controlling pain and writing. The results demonstrated a heroism that opens new avenues to our consideration of what constitutes creativity in human lives.

Unit Cohesion,Resilience, and Mental Health of Soldiers in Basic Combat Training

Military unit cohesion has been shown to correlate with physical and psychological outcomes. However, little is known about the development of cohesion in the early days of military service during Basic Combat Training (BCT) and how it relates to positive support and the negative stressors of training. The current study assessed the development of unit cohesion across the 10-week BCT period (N = 1,939), and the relation of cohesion to stress, resilience, mental health measures, and BCT outcomes (graduation, passing the Army Physical Fitness Test, and final Basic Rifle Marksmanship scores). The sample was primarily male (62%), under age 25 (88%), and unmarried (88%). All putative mediators showed significant change over time. Unit cohesion increased over time (slope 0.22; p < .001), and these increases were associated with decreases in psychological distress (p < .001), sleep problems (p < .001), and tolerance of BCT stressors (p < .001), as well as increases in resilience (p < .001), confidence managing stress reactions (p < .001), and positive states of mind (p < .001). Unit cohesion was indirectly associated with successful graduation and passing the Army Physical Fitness Test through cohesion-related improvement in psychological distress, resilience, and confidence managing reactions to stress. Sleep problems also mediated BCT graduation. Cohesion effects on the Basic Rifle Marksmanship scores were mediated by psychological distress and tolerance of BCT stressors only. These results suggest that unit cohesion may play a key role in the development of psychological health among new soldiers.     

Predictors of Support for Women in Military Roles: Military Status,Gender, and Political Ideology

The repeal of combat restrictions by gender raises the importance of understanding factors related to the acceptance of women serving in the full range of military jobs. Previous research shows military affiliated cadets, especially males, are substantially less approving of women serving in military jobs, especially those involving exposure to direct combat or command positions, than are other college students. The current study extends these findings by considering political ideology in addition to gender and military affiliation, as related to attitudes toward women’s roles in the military overall and in combat roles in particular. Survey data from Service Academy cadets (n = 3,116), Reserve Officer Training Corps (ROTC) cadets (n = 1,367), and nonmilitary affiliated college students (n = 2,648), provided measures of whether a woman should or should not be allowed to serve in 9 different military job areas. In addition to overall approval, a scale for combat jobs was created from a subset of 4 of the jobs. Regression analysis indicated that once gender, political party, political position (left/right), and attitudes toward mothers in the workforce overall were controlled, type of college did not add to the prediction of acceptance of women in various military roles. In general, nonmilitary affiliated respondents, women, and those identifying as Democrat offered higher approval scores. Our findings suggest more aggressive programs, designed to educate and socialize these future leaders about women’s roles in the military, may require development.     

Personality Factors,Family Structure,and Sex of Drawn Figure on the Draw-A-Person Test

One hundred seventy-four youthful psychiatric inpatients were given the Draw-A-Person Test (DAP) as part of an assessment battery. Sex of person drawn was compared to subject's sex, Achenbach aggression and delinquency scores, and scores on Children's Inventory of Anger and Nowicki-Strickland Locus of Control Scale. The sex of the person drawn was also compared to family composition, specifically whether or not the child came from an intact family with both a male and female parent or role model. Results support drawing of a same-sexed individual as normative, regardless of age or sex. Adolescent girls and young boys were the only groups that differed significantly from this norm. Personality measures and family composition were not significantly related to the tendency to draw same versus opposite sex.     

Support for religio‐political aggression among teenaged boys in Gaza: Part I: psychological findings

Politically aggressive militant groups usually rely on support from a larger community, although evidence suggests that only some members of that larger community support that aggression. A major subtype of political aggression is that associated with religious differences—or Religio‐Political Aggression (RPA). Little previous research has explored demographic or psychological factors that might distinguish supporters from non‐supporters of RPA. In an exploratory study, we investigated whether factors previously associated with aggression might correlate with support for RPA in the case of the Israeli/Palestinian conflict. During the second intifada, fifty‐two 14‐year‐old Palestinian boys in Gaza completed self‐report measures of life events, emotional status, and political attitudes. Teenaged boys who reported family members having been wounded or killed by the Israeli Defense Forces (IDF) expressed greater support for RPA (t(50)=?2.30, P=.026). In addition, boys who felt their group was treated unjustly reported greater support for RPA compared with those who did not (t(50)=?2.273, P=.027). Implications of these preliminary data are discussed. Aggr. Behav. 36:219–231, 2010. © 2010 Wiley‐Liss, Inc.     

Contextual interference effects in sequence learning for young and older adults

Practice of different tasks in a random order induces better retention than practicing them in a blocked order, a phenomenon known as the contextual interference (CI) effect. Our purpose was to investigate whether the CI effect exists in sequence learning, such that practicing different sequences in a random order will result in better learning of sequences than practicing them in blocks, and whether this effect is affected by aging. Subjects practiced a serial reaction time task where a set of three 4-element sequences were arranged in blocks or in a random order on 2 successive days. Subjects were divided into 4 groups based on a 2-GROUP (young or old) by 2-ORDER (random or blocked practice) between-subject design. Three days after practice (Day 5), subjects were tested with practiced and novel sequences to evaluate sequence-specific learning. The results replicate the CI effect in sequence learning in both young and older adults. Older adults retained sequences better when trained in a random condition than in a blocked condition, although the random condition incurs greater task switching costs in older adults during practice. Our study underscores the distinction between age-related effects on learning vs. performance, and offers practical implications for enhancing skill learning in older adults.     

Influences of maternal postpartum depression on fathers and on father–infant interaction

Maternal postpartum depression (PPD) has been shown to negatively influence mother–infant interaction; however, little research has explored how fathers and father–infant interaction are affected when a mother is depressed. This study examined the influence of maternal PPD on fathers and identified maternal and paternal factors associated with father–infant interaction in families with depressed as compared with nondepressed mothers. A convenience sample of 128 mother–father–infant triads, approximately half of which included women with significant symptoms of PPD at screening, were recruited from a screening sample of 790 postpartum women. Mothers and fathers completed measures of depression, marital satisfaction, and parenting stress at 2 to 3 months' postpartum and were each videotaped interacting with their infants. Results indicate that maternal PPD is associated with increased paternal depression and higher paternal parenting stress. Partners of depressed women demonstrated less optimal interaction with their infants, indicating that fathers do not compensate for the negative effects of maternal depression on the child. Although mother–infant interaction did not influence father–infant interaction, how the mother felt about her relationship with the infant did, even more so than maternal depression. The links between maternal PPD, fathers, and father–infant interaction indicate a need for further understanding of the reciprocal influences between mothers, fathers, and infants.
