The femininization of the female oedipal complex, Part II: Aggression reconsidered

This paper examines and explores the manifestations of aggressive impulses in the so-called female oedipal complex. The authors describe how competitive aggression on the part of young girls, seemingly missing in children's stories and myths, is unconsciously inhibited, disguised, or externalized. They report similar phenomena in women patients involved in triangular conflicts, and present a selected review of the literature on the inhibition of aggression within the female triangular situation. Stressing dynamic patterns in the object relationships in the female triangular situation, the authors offer a psychological explanation for this inhibition. They present clinical material to demonstrate how overt murderous and competitive aggression toward the mother appears after considerable analytic work. They conclude that girls and women frequently relinquish a sense of agency over both aggression and sexuality in dealing with triangular conflicts, to preserve a safe relationship with their mothers.     

Context-processing deficits in schizotypal personality disorder

Research suggests that schizotypal personality disorder (SPD) is a part of the spectrum of schizophrenia-related illnesses. This article hypothesizes that a deficit in the representation and maintenance of context is a core cognitive disturbance in schizophrenia and that SPD individuals should demonstrate context-processing deficits. To test this hypothesis, the authors administered 3 versions of their AX-CPT task, designed to assess context processing, to 35 healthy controls and 26 individuals with DSM-IV SPD. They also administered working memory and selective attention tasks. SPD individuals displayed context representation deficits similar to those found in schizophrenia but did not show the same additional deficits in context maintenance. Context processing was strongly associated with working memory and selective attention performance in the SPD individuals.     

Topic—vehicle interaction in metaphor comprehension

Property comparison models of metaphor comprehension assume that the topic and vehicle terms in metaphors are both understood to be referring to their conventional literal referents. In contrast, the interactive property attribution model (Glucksberg, McGlone, & Manfredi, 1997) assumes that the vehicle is understood to be referring to a metaphoric category that includes the topic's literal referent as a member. A priming paradigm was used to test the implications of these different models. Prior to interpreting a metaphor, participants read (1) the topic or vehicle concept alone, (2) a sentence ascribing a metaphor-relevant property to one concept, or (3) a sentence ascribing a metaphor-irrelevant property to one concept. All of the prime types facilitated metaphor comprehension with the exception of sentences ascribing metaphor-irrelevant properties to vehicles. The failure of these sentences (but not their topic counterparts) to facilitate metaphor comprehension is attributable to their priming an inappropriate literal interpretation of the vehicle term. These results are consistent with the claim that irrelevant information is suppressed during language comprehension (Gernsbacher, 1990) and support the interactive property attribution model.     

The neural circuitry supporting goal maintenance during cognitive control: a comparison of expectancy AX-CPT and dot probe expectancy paradigms

Goal maintenance is an aspect of cognitive control that has been identified as critical for understanding psychopathology according to criteria of the NIMH-sponsored CNTRICS (Cognitive Neuroscience Treatment Research to Improve Cognition in Schizophrenia) and Research Domain Criteria (RDoC) initiatives. CNTRICS proposed the expectancy AX-CPT, and its visual-spatial parallel the dot probe expectancy (DPX), as valid measures of the cognitive and neural processes thought to be relevant for goal maintenance. The goal of this study was to specifically examine the functional neural correlates and connectivity patterns of both goal maintenance tasks in the same subset of subjects to further validate their neural construct validity and clarify our understanding of the nature and function of the neural circuitry engaged by the tasks. Twenty-six healthy control subjects performed both the letter (AX) and dot pattern (DPX) variants of the CPT during fMRI. Behavioral performance was similar between tasks. The 2 tasks engaged the same brain networks including dorsolateral prefrontal cortex (DLPFC) and dorsal parietal regions, supporting their validity as complementary measures of the goal maintenance construct. Interestingly there was greater engagement of the frontal opercular insula region during the expectancy AX-CPT (letter) and greater functional connectivity between the PFC and medial temporal lobe in the DPX (dot pattern). These differences are consistent with differential recruitment of phonological and visual-spatial processes by the two tasks and suggest that additional long-term memory systems may be engaged by the dot probe version.     

Anhedonia and the experience of emotion in individuals with schizophrenia

Research shows that individuals with schizophrenia report symptoms of anhedonia when assessed by interview or questionnaire. However, when presented with emotional stimuli, they report emotional experiences that are similar to those of control participants. The authors hypothesized that deficits in working memory and episodic memory contribute to such discrepancies. They administered measures of working and episodic memory, self-report anhedonia questionnaires, and several types of emotional stimuli to 49 individuals with schizophrenia and 47 control participants. All participants reported experiencing similar amounts of pleasant-unpleasant emotion (valence) in response to stimuli, but individuals with schizophrenia reported experiencing less arousal for negative stimuli. Individuals with schizophrenia also reported greater social and physical anhedonia on a traditional anhedonia questionnaire. Disturbances in working memory moderated the relationship between physical anhedonia and participants' emotional experience of positive stimuli.     

The neural correlates of social attention: automatic orienting to social and nonsocial cues

Previous evidence suggests that directional social cues (e.g., eye gaze) cause automatic shifts in attention toward gaze direction. It has been proposed that automatic attentional orienting driven by social cues (social orienting) involves a different neural network from automatic orienting driven by nonsocial cues. However, previous neuroimaging studies on social orienting have only compared gaze cues to symbolic cues, which typically engage top-down mechanisms. Therefore, we directly compared the neural activity involved in social orienting to that involved in purely automatic nonsocial orienting. Twenty participants performed a spatial cueing task consisting of social (gaze) cues and automatic nonsocial (peripheral squares) cues presented at short and long stimulus (cue-to-target) onset asynchronies (SOA), while undergoing fMRI. Behaviorally, a facilitation effect was found for both cue types at the short SOA, while an inhibitory effect (inhibition of return: IOR) was found only for nonsocial cues at the long SOA. Imaging results demonstrated that social and nonsocial cues recruited a largely overlapping fronto-parietal network. In addition, social cueing evoked greater activity in occipito-temporal regions at both SOAs, while nonsocial cueing recruited greater subcortical activity, but only for the long SOA (when IOR was found). A control experiment, including central arrow cues, confirmed that the occipito-temporal activity was at least in part due to the social nature of the cue and not simply to the location of presentation (central vs. peripheral). These results suggest an evolutionary trajectory for automatic orienting, from predominantly subcortical mechanisms for nonsocial orienting to predominantly cortical mechanisms for social orienting.     

The tenacious nature of memory binding for arousing negative items

In two experiments, we investigated whether people are better or worse at updating memory for the location of emotional pictures than of neutral pictures. We measured participants’ memories for the locations of both arousing negative pictures and neutral pictures while manipulating practice (encountering the same event repeatedly) and interference (encountering the same picture in a different location). Memory for the context of emotional items was less likely to be corrected when erroneous and was less likely to be correctly updated when the context changed. These results suggest that initial item-context binding is more tenacious for emotional items than for neutral items, even when such binding is incorrect.     

Social and personal determinants of workplace aggression: Evidence for the impact of perceived injustice and the Type A Behavior Pattern

Four hundred fifty‐two employed persons rated the frequency with which they had been the victims of a wide range of aggressive actions at work. In addition, they also rated the frequency with which they themselves had aggressed against others in their workplaces. Three hypotheses were investigated: (1) covert forms of aggression, in which aggressors seek to conceal their identity from target persons, are significantly more frequent in workplaces than overt forms of aggression; (2) the greater the perceived injustice reported by employees, the greater their tendency to engage in workplace aggression; and (3) the higher individuals' scores on a measure of the Type A Behavior Pattern, the greater their reported frequency of engaging in various forms of workplace aggression. Results offered support for all three hypotheses. In addition, several demographic variables (participants' age and gender; the physical location of their workplaces) were also found to play a role in the occurrence of workplace aggression. Together, these findings were interpreted as underscoring the importance of establishing close conceptual links between research on workplace aggression and basic research on human aggression. Aggr.
