The Development of Aggression in 18 to 48 Month Old Children of Alcoholic Parents

This study examined the development of aggressive and oppositional behavior among alcoholic and nonalcoholic families using latent growth modeling. The sample consisted of 226 families assessed at 18, 24, 36, and 48 months of child age. Results indicated that children in families with nonalcoholic parents had the lowest levels of aggressive behavior at all time points compared to children with one or more alcoholic parents. Children in families with two alcoholic parents did not exhibit normative decreases in aggressive behavior from 3 to 4 years of age compared to nonalcoholic families. However, this association was no longer significant once a cumulative family risk score was added to the model. Children in families with high cumulative risk scores, reflective of high parental depression, antisocial behavior, negative affect during play, difficult child temperament, marital conflict, fathers’ education, and hours spent in child care, had higher levels of aggression at 18 months than children in low risk families. These associations were moderated by child gender. Boys had higher levels of aggressive behavior at all ages than girls, regardless of group status. Cumulative risk was predictive of higher levels of initial aggressive behavior in both girls and boys. However, boys with two alcoholic parents had significantly less of a decline in aggression from 36 to 48 months compared to boys in the nonalcoholic group.     

Les passions de l'ame: on obsessive and harmonious passion

Passion is defined as a strong inclination toward an activity that people like, that they find important, and in which they invest time and energy. Two types of passion are proposed: obsessive and harmonious. Obsessive passion (OP) refers to a controlled internalization of an activity in one's identity that creates an internal pressure to engage in the activity that the person likes. Harmonious passion (HP) refers to an autonomous internalization that leads individuals to choose to engage in the activity that they like. HP promotes healthy adaptation whereas OP thwarts it by causing negative affect and rigid persistence. Results from four studies involving more than 900 participants from different populations supported the proposed conceptualization.     

Processing emotional tone from speech in Parkinson’s disease: A role for the basal ganglia

In this study, individuals with Parkinson's disease were tested as a model for basal ganglia dysfunction to infer how these structures contribute to the processing of emotional speech tone (emotional prosody). Nondemented individuals with and without Parkinson's disease (n = 21/group) completed neuropsychological tests and tasks that required them to process the meaning of emotional prosody in various ways (discrimination, identification, emotional feature rating). Individuals with basal ganglia disease exhibited abnormally reduced sensitivity to the emotional significance of prosody in a range of contexts, a deficit that could not be attributed to changes in mood, emotional-symbolic processing, or estimated frontal lobe cognitive resource limitations in most conditions. On the basis of these and broader findings in the literature, it is argued that the basal ganglia provide a critical mechanism for reinforcing the behavioral significance of prosodic patterns and other temporal representations derived from cue sequences (Lieberman, 2000), facilitating cortical elaboration of these events.     

The LSARS-II: Lethality of Suicide Attempt Rating Scale-Updated

The concept of lethality is essential to the assessment of suicide risk; yet operational definitions of lethality for purposes of its measurement have been loose and varied. A number of scaling measures have been published in the literature, with no relative consensus on the best of these. In addition, only a few of these scales have published data on their psychometric properties. Of these, we argue that the best is the Lethality of Suicide Attempt Rating Scale (LSARS; Smith, Conroy, & Ehler, 1984). Presented here is a significantly revised and redesigned listing of drugs and chemicals and lethal ranges of ingestion (in caps, tabs, or ounces) by body weight to update that scale.     

Desensitization of postsynaptic glutamate receptors contributes to high-frequency homosynaptic depression of aplysia sensorimotor connections

Withdrawal reflexes of Aplysia are mediated in part by a monosynaptic circuit of sensory (SN) and motor (MN) neurons. A brief high-frequency burst of spikes in the SN produces excitatory postsynaptic potentials (EPSPs) that rapidly decrease in amplitude during the burst of activity. It is generally believed that this and other (i.e., low-frequency) forms of homosynaptic depression are entirely caused by presynaptic mechanisms (e.g., depletion of releasable transmitter). The present study examines the contribution that desensitization of postsynaptic glutamate receptors makes to homosynaptic depression. Bath application of cyclothiazide, an agent that reduces desensitization of non-NMDA glutamate receptors, reduced high-, but not low-frequency synaptic depression. Thus, a postsynaptic mechanism, desensitization of glutamate receptors, can also contribute to homosynaptic depression of sensorimotor synapses.     

Interpersonal and noninterpersonal interactions, interpersonal motives, and the effect of frustrated motives

A new circumplex model of interpersonal interaction emphasizes the motives that drive interpersonal behaviors and the negative affect (such as anger) that occurs when a strongly activated motive is frustrated. This study examined the model experimentally by varying conditions designed to activate and frustrate interpersonal motives. One hundred twenty-nine students engaged in text-based discussions using a computer. Three factors were varied: (a) activation of interpersonal motives--participants believed the interaction was interpersonal (with a human) or noninterpersonal (with a computer); (b) individual differences in motive activation--assertive and nonassertive participants were compared (strong vs. weak motive to influence others); and (c) level of frustration of activated motives--the "partner's" messages contained dominating or nondominating language. Participants who believed their interaction was interpersonal produced more interpersonal behaviors of various types. Assertive participants who interacted with a dominating and apparently human partner produced a disproportionate amount of hostility, indicating anger ascribed to frustrated motives.     

The emotional impact and ease of recall of warning signs for suicide: a controlled study

In light of concerns about potential iatrogenic effects of information about suicide, in the current study we examined the emotional impact of reading a list of warning signs for suicide in comparison to comparable lists for heart attacks and diabetes. All participants read two sets of warning signs, with the experimental group reading the suicide warning signs. Results confirm no difference in emotional impact across groups, along with providing evidence that warning signs for suicide are as easy to recall after exposure as warning signs for heart attack. Implications for pubic health campaigns are discussed.     

Warning signs for suicide on the Internet: a descriptive study

The issue of suicide warning signs on the Internet is considered. In addition to reviewing some of the relevant conceptual issues about warning signs, a random sample of Internet sites was selected and reviewed. Warning signs were grouped and agreement across sites was examined, with results confirming broad disparity in what is presented to the public. The implications of a lack of consensus on warning signs for suicide are discussed.     

Gender influences as an impediment to knowledge sharing: when men and women fail to seek peer feedback

Little research has considered how work team characteristics influence feedback-seeking behavior among team members. The authors' aim in this research was to identify central sources of influence on feedback-seeking behavior in a mixed-gender context. They placed men and women in work groups of varying gender composition. The participants then participated in a gender-biased (perceived as either male-oriented or female-oriented) negotiation exercise. Findings indicated that the gender of the participant, the team's gender composition, and the gender orientation of the task influenced feedback-seeking behavior among team members.     

A psychologist grows in Brooklyn: reflections from the past

In this autobiography, I begin by describing how I made many important decisions in my life without much conscious or verbalized thought. I cover information about my parents, grandparents, early school experiences, and both college and graduate school. The autobiography also includes a detailed discussion of my 41 years of teaching at the University of Tennessee. I discuss important experiences that helped me to become a clinical psychologist and a teacher. I conclude the article with a personal experience concerning the death of my mother and an early memory.
