Self-control relies on glucose as a limited energy source: willpower is more than a metaphor

The present work suggests that self-control relies on glucose as a limited energy source. Laboratory tests of self-control (i.e., the Stroop task, thought suppression, emotion regulation, attention control) and of social behaviors (i.e., helping behavior, coping with thoughts of death, stifling prejudice during an interracial interaction) showed that (a) acts of self-control reduced blood glucose levels, (b) low levels of blood glucose after an initial self-control task predicted poor performance on a subsequent self-control task, and (c) initial acts of self-control impaired performance on subsequent self-control tasks, but consuming a glucose drink eliminated these impairments. Self-control requires a certain amount of glucose to operate unimpaired. A single act of self-control causes glucose to drop below optimal levels, thereby impairing subsequent attempts at self-control.     

New strings for old: The role of similarity processing in an incidental learning task

This paper reports three experiments that examine the role of similarity processing in McGeorge and Burton's (1990) incidental learning task. In the experiments subjects performed a distractor task involving four-digit number strings, all of which conformed to a simple hidden rule. They were then given a forced-choice memory test in which they were presented with pairs of strings and were led to believe that one string of each pair had appeared in the prior learning phase. Although this was not the case, one string of each pair did conform to the hidden rule. Experiment 1 showed that, as in the McGeorge and Burton study, subjects were significantly more likely to select test strings that conformed to the hidden rule. However, additional analyses suggested that rather than having implicitly abstracted the rule, subjects may have been selecting strings that were in some way similar to those seen during the learning phase. Experiments 2 and 3 were designed to try to separate out effects due to similarity from those due to implicit rule abstraction. It was found that the results were more consistent with a similarity-based model than implicit rule abstraction per se.     

Moderating effects of harasser status and target gender on the relationship between unwanted sexual attention and overall job satisfaction

Despite a vast body of literature evidencing the negative effects of workplace sexual harassment it remains unclear whether sexual harassment experienced by the target is worse when the harasser is a supervisor, rather than a coworker. With a scenario‐based experimental study we examined whether targets harassed by their supervisor would experience greater decreases in overall job satisfaction than those targeted by a coworker. Results suggested that harasser status moderated the effects of sexual harassment on overall job satisfaction but only for female targets. Further, the effect of supervisor harassment on job satisfaction was mediated by interpersonal justice perceptions.     

The danger in deception: oedipal betrayal and the assault on truth

Certain potential precursors to heterosexual women's experience of partner infidelity are explored as these dynamics unfold within the oedipal crisis-the "betrayal" by the oedipal objects. As each child moves into the oedipal phase, he or she comes to recognize not only desire for the mother, but the mother's desire for the father. A doubling of this experience of "deception," encountered first in relation to the mother, and then repeated with the father, may be especially pronounced for a girl, as she is likely to inhabit more fully her bisexual potential in negotiating the expected shift of object choice from mother to father. "Deceived" by her primary maternal oedipal object, a girl sets forth toward her paternal oedipal object with "fidelity" already an issue, and with faith in her mind's ability to determine reality already shaken. Undermined trust in self and other is the context in which she begins the oedipal relation to her heterosexual object. This path is quite distinct from that traveled by the heterosexual boy. Clinical material illustrates the assault on one's mind, on one's confidence to determine what is true, that is a central aspect of both oedipal and adult betrayal.     

How central is the alliance in psychotherapy? A multilevel longitudinal meta-analysis

Prior meta-analyses have found a moderate but robust relationship between alliance and outcome across a broad spectrum of treatments, presenting concerns, contexts, and measurements. However, there continues to be a lively debate about the therapeutic role of the alliance, particularly in treatments that are tested using randomized clinical trial (RCT) designs. The purpose of this present study was to examine whether research design, type of treatment, or author's allegiance variables, alone or in combination, moderate the relationship between alliance and outcome. Multilevel longitudinal analysis was used to investigate the following moderators of the alliance-outcome correlation: (a) research design (RCT or other), (b) use of disorder-specific manuals, (c) specificity of outcomes, (d) cognitive and/or behavioral therapy (CBT) or other types of treatments, (e) researcher allegiance, and (f) time of alliance assessment. RCT, disorder-specific manual use, specificity of primary and secondary outcomes, and CBT did not moderate the alliance-outcome correlation. Early alliance-outcome correlations were slightly higher in studies conducted by investigators with specific interest in alliance than were those in studies conducted by researchers without such an allegiance. Over the course of therapy, these initial differences disappeared. Apart from this trend, none of the variables previously proposed as potential moderators or mediators of the alliance-outcome relation, alone or in combination, were found to have a mediating impact.     

Agentic and communal traits and health: adolescents with and without diabetes

The authors examined whether agentic and communal traits are associated with relationship and health outcomes among adolescents with and without diabetes. They interviewed 263 teens (average age 12; 132 Type 1 diabetes; 131 healthy) on an annual basis for 5 years. The authors measured agency, communion, unmitigated agency, and unmitigated communion as well as parent and peer relationship quality, psychological distress, and diabetes health. In concurrent and lagged multilevel models, unmitigated communion and unmitigated agency were associated with poor relationship outcomes and greater psychological distress for those with and without diabetes. In lagged analyses, unmitigated communion predicted deterioration in diabetes health. Communion and agency were associated with positive relationship and health outcomes, with the former being stronger than the latter. These results underscore the need to focus on unmitigated agency and unmitigated communion when studying the implications of personality for health during adolescence.     

Implications of Psychosocial Factors for Diabetes Outcomes among Children with Type 1 Diabetes: A Review

We adopt a risk and resistance framework to review the literature on the psychosocial factors that influence diabetes outcomes—specifically self‐care behavior (blood glucose monitoring, diet, exercise, insulin administration) and glycemic control. We examine both personal and social/environmental risk and resistance factors. We conclude by suggesting conceptual and methodological directions for future research. Conceptually, we suggest that researchers examine the synergy among variables that cut across domains, mechanisms linking psychosocial factors to diabetes outcomes, and the impact of goals on health. Methodologically, we suggest that researchers examine age, gender, and race as moderator variables; utilize momentary data collection technology; and employ more sophisticated longitudinal analyses.     

MOTOR PREPARATION,MOTOR EXECUTION,ATTENTION, AND EXECUTIVE FUNCTIONS IN ATTENTION DEFICIT/HYPERACTIVITY DISORDER (ADHD)

Attention and executive functions were investigated in medicated and unmedicated children with ADHD combined type using a novel selective reaching task. This task involved responding as rapidly as possible to a target while at times having to ignore a distractor. Results indicated that unmedicated children with ADHD showed slow and inaccurate responding. Slow responding reflected problems at the stage of movement preparation but not movement execution. An attentional impairment, rather than a motor planning problem per se, appeared to underlie the slow movement preparation. Inaccurate responding reflected problems with response inhibition and selective attention, impulsivity, set-shifting, and difficulties in maintaining vigilance. Although medicated children with ADHD did not show slow movement preparation, they did show some response inaccuracy, resulting especially from impulsive responding.These findings suggest that ADHD is characterized by slow motor preparation (but not motor execution), and deficits in selective attention, vigilance, and executive functions. Preliminary results suggest that stimulant medication may resolve some of these motor, attentional and executive function deficits.     

Aging Extends the Time Required to Switch Cognitive Set

ABSTRACT

The Attentional Blink (AB) refers to a decrease in the chance of detecting a second target in a rapid sequence of items if it occurs within approximately 500 ms of a first target. In this study the efficiency of establishing and switching cognitive set for older adults (mean age 71.62 years) relative to young adults (mean age 21.33 years) was investigated. Three increasingly complex conditions of the AB paradigm were employed, each of which required participants to identify a coloured square (T1) and a letter (T2) within a stream of distracters. Accuracy of identification of T2 decreased for both young and older adults as complexity increased. In Condition 1, selection criteria for both targets were fully specified, while T1 acted as a direct cue to the selection criteria for T2 in Condition 2. Older participants took longer to establish cognitive set in this condition. Condition 3 contained an added requirement to activate a pre-determined rule for T2 selection. The basic requirement to establish cognitive set ‘online’, however, seemed to disguise any additional potential problems associated with the additional load required for Condition 3 for older adults. Younger adults were cognitively slowed in Condition 3 relative to Condition 2, suggesting that it is the need to use an internally generated cue to switch cognitive set that requires extra time for them. The significantly larger AB demonstrated by the older participants indicated an impaired ability to rapidly establish cognitive set. The findings are discussed in light of the current literature on cognitive aging, the AB and task switching.
