Lateral inhibition and echoic memory: Some comments on Crowder’s (1978) theory

Crowder (1978) has proposed a theory of the suffix effect based on lateral inhibition among echoic representations of the list and suffix items. The theory was prompted by, and derives its principal support from, the counterintuitive finding that the effect is smaller with multiple suffixes than with a conventional single suffix. In this paper, we describe four experiments, each of which fails to replicate this finding. In addition, we note a prediction of the theory and show that it is contrary to available evidence. It is argued that the details of the suffix effect are too complex to be captured by a theory of peripheral mechanism, even one as ingenious as Crowder’s.     

Using the shifting standards model of stereotype-based judgments to examine the impact of race on compensation decisions

The Shifting Standards Model (SSM) of stereotypic judgments is presented as a model of implicit bias that produces a psychological mechanism contributing to continued racial wage disparities. The SSM is used to explain race-based differences in subjective evaluations of compensation decisions. We report three experimental studies in which research participants made compensation decisions for either a White or Black employee. Across three studies, participants judged a Black employee's raise as subjectively better than a comparably described White employee's raise. Participants who work in Human Resources fields (Study 3) and those with experience making compensation decisions (Study 2) were as likely as other participants to show evidence of the shifting standards effect. The findings are discussed in the context of individual implicit biases contributing to continued wage disparities and potential organizational practices to ameliorate these influences.

Belief in good luck and psychological well-being: the mediating role of optimism and irrational beliefs

The authors examined the relationship of belief in good luck with depression and anxiety within the context of a number of cognitive and personality variables used to explain depression and anxiety. Undergraduate students (46 men, 98 women) were administered measures of belief in good luck, depression, anxiety, optimism, neuroticism, attribution style, self-esteem, and irrational beliefs. The results showed that belief in good luck was significantly related to optimism and irrational beliefs. A number of models were tested to determine whether irrational beliefs or optimism mediated the relationship between belief in good luck and depression and anxiety. The findings suggested that negative relationships between belief in good luck and both depression and anxiety are best addressed by the theory that belief in good luck engenders optimistic traits and a reduced level of irrational beliefs.     

Rumination and overgeneral memory in depression: effects of self-focus and analytic thinking

Previous research has shown that, compared with a rumination induction, a brief distraction procedure reduces overgeneral autobiographical memory in depression. The authors investigated whether this effect depends on reductions in analytic thinking or reductions in self-focus. Focus of attention (high vs. low self-focus) and thinking style (high vs. low analytical thinking) were independently manipulated in depressed patients in a 2 x 2 design. Autobiographical recall was measured pre- and postmanipulation. Thinking style significantly affected overgeneral memory, whereas focus of attention significantly affected despondent mood. Reducing analytical self-focus reduced overgeneral memory, suggesting that high levels of naturally occurring ruminative analytic thinking may be important in the maintenance of overgeneral memory. Overgeneral memory in depression may be associated with chronic ruminative attempts to make sense of current or past difficulties.     

“Socializing” Achievement Goal Theory: The Need for Social Goals

Cultures shape the types of goals that students pursue in the classroom. However, research in achievement goal theory seems to have neglected this cultural aspect with its exclusive focus on individualistically-based goals such as mastery and performance goals. This emphasis on mastery and performance goals may reflect Western individualist psychological thinking. Thus, social goals, which may be more salient in collectivist cultures, are relatively neglected. There is a dearth of studies investigating the role of social goals in academic motivation, and the few studies that did explore them are somewhat problematic. This paper reviews research done within the achievement goal theory, considers the need for more studies on social goals, and concludes with the argument that social goals are important in understanding student motivation especially in collectivist cultures.     

Supporting the Need for an Integrated System of Care for Youth with Co-occurring Traumatic Stress and Substance Abuse Problems

Adolescents are at high risk for violence exposure and initiation of drug use. Co-occurring substance use and trauma exposure are associated with increased risk of mental health disorders, school underachievement, and involvement with multiple systems of care. Coordination and integration of systems of care are of utmost importance for these vulnerable youth. This study delineates the negative sequelae and increased service utilization patterns of adolescents with a history of trauma, substance abuse, and co-occurring trauma and substance abuse to support the need for integrated mental health and substance abuse services for youth. Data from two national sources, the National Child Traumatic Stress Network and Center for Substance Abuse Treatment demonstrate the increased clinical severity (measured by reports of emotional and behavioral problems), dysfunction, and service utilization patterns for youth with co-occurring trauma exposure and substance abuse. We conclude with recommendations for an integrated system of care that includes trauma-informed mental health treatment and substance abuse services aimed at reducing the morbidity and relapse probability of this high-risk group.     

Co-localisation of abnormal brain structure and function in specific language impairment

We assessed the relationship between brain structure and function in 10 individuals with specific language impairment (SLI), compared to six unaffected siblings, and 16 unrelated control participants with typical language. Voxel-based morphometry indicated that grey matter in the SLI group, relative to controls, was increased in the left inferior frontal cortex and decreased in the right caudate nucleus and superior temporal cortex bilaterally. The unaffected siblings also showed reduced grey matter in the caudate nucleus relative to controls. In an auditory covert naming task, the SLI group showed reduced activation in the left inferior frontal cortex, right putamen, and in the superior temporal cortex bilaterally. Despite spatially coincident structural and functional abnormalities in frontal and temporal areas, the relationships between structure and function in these regions were different. These findings suggest multiple structural and functional abnormalities in SLI that are differently associated with receptive and expressive language processing.
