Distinguishing instrumental and hostile aggression: Does it make a difference?

An analogue task of instrumental and hostile aggression during a competitive game, modified to minimize overlap between aggressive responses, was evaluated in 8- to 14-year-old clinically referred boys (n=33). Postgame interviews indicated that the hostile response, an aversive noise, was perceived by over 80% of subjects as hostile and not instrumental. In contrast, the instrumental response, blocking the opponent's game, was perceived about equally as having instrumental and hostile functions. The hostile aggressive response was uniquely correlated with continuous performance task impulsive commission errors (r=51), which supported the theoretical relation of hostile aggression to poor impulse control. These results suggest that instrumental and hostile aggression can be distinguished and when precisely defined are distinct in theoretically important ways.The authors are grateful to Mary Milnamow, Susan Panichelli, Nancy Benzal, Elissa Batshaw, and Nancy Stone for assistance in data collection.

Free-time as a consequence for behavior in classroom settings: A critical review

Osborne (1969) presented adolescent hearing impaired students with five minutes of free- time contingent upon remaining seated for 15 minutes in the classroom. This procedure substantially reduced the frequency of out- of- seat behavior. Since the publication of this seminal work, 49 studies have used free- time as a consequence to change behavior. This review critically examines these 49 studies. The review shows that free-time has been used effectively with a variety of different behaviors and student populations, and with different methods of delivery. Based on a synthesis of information from the review, optimal methods for the use of free-time are suggested. Finally, it is concluded that additional research is needed, especially to answer the question of why free-time is effective.     

Applying propensity score matching to assess the impact of the pandemic on intimate relationships

The COVID-19 pandemic produced multiple stressors that risk relationship conflict and dissatisfaction. We extended prior studies that yielded inconsistent effects of the pandemic on relationships by using propensity score matching to (1) compare levels of relationship conflict and satisfaction during the pandemic (pandemic group; N = 7268) to similar people immediately before the pandemic (matched control group; N = 7268), and (2) compare pandemic groups facing different types of restrictions, beginning with lockdowns involving household isolation to returning to normal life. Results reveal that relationship conflict increased and relationship satisfaction decreased in response to the pandemic, but these effects were very small and primarily occurred in the initial stages of the pandemic when lockdown involved household isolation. The results add to evidence of resilience in personal and relationship well-being in 2020, but also indicate the importance of understanding the effects of varying pandemic-related conditions across the years of the pandemic.     

Interrater reliability and coding guide for nonpsychotic formal thought disorder

Reliable and valid assessment of abnormal speech patterns may enable earlier recognition of nonpsychotic disorders through characteristic speech patterns. This study sought to establish interrater reliability using a standardized guide for scoring. A scoring guide defining 27 elements (e.g., inappropriate self-reference, simple loss of goal, circumstantiality) of disordered thought was developed. The seminal work of Andreasen's and Holzman's groups provided 12 elements, and 15 new elements were suggested by clinical literature. Audiotaped interviews with 12 psychiatric inpatients, adults of both sexes and various ages hospitalized for acute management of nonpsychotic psychiatric disorders, provided speech samples for observation of disordered thought by two independent raters. Using the guide's definitions and accompanying examples of elements of disordered thought, reliability in scoring was high (kappa of .85 for agreement on the presence of any abnormal speech element and kappa values from .66 to 1.00 for agreement on the presence of individual elements).     

Age and distraction by telephone conversation in task performance: implications for use of cellular telephones while driving

Predicted to diminish task performance were (a) distraction by telephone conversation and (b) older age. 38 participants pointed to letters on a randomized or alphabetized letter matrix during distraction by telephone conversation or no distraction. In a within-subjects design, telephone conversation negatively affected completion time but there were no age differences. Implications for cellular telephone use while driving are discussed.     

Richard Zaner’s Phenomenology of the Clinical Encounter

The clinical ethics propounded by Richard Zaner is unique. Partly because of his phenomenological orientation and partly because of his own daily practice as a clinical ethicist in a large university hospital, Zaner focuses on the particular concrete situations in which patients and their families confront illness and injury and struggle toward workable ways for dealing with them. He locates ethical reality in the clinical encounter. This encounter encompasses not only patient and physician but also the patients family and friends and indeed the entire lifeworld in which the patient is still striving to live. In order to illuminate the central moral constituents of such human predicaments, Zaner discusses the often-overlooked features of disruption and crisis, the changed self, the patients dependence and the physicians power, the violation of personal boundaries and their necessary reconfiguring, and the art of listening.     

The Role of Life Stress and Social Support in the Adjustment of Sexually Victimized Pregnant and Parenting Minority Adolescents

Associations among sexual victimization and the psychosocial functioning of African American and Latina pregnant and parenting adolescents were examined. Forty-seven (17.7%) of the 265 participants reported histories of sexual victimization, most of which was unwanted sexual intercourse. The victimized adolescents reported higher levels of depression, anxiety, and life stress and, although the two groups reported no differences in their levels of social support, support was found to be differentially related to depression and anxiety in the two groups. In particular, victims derived benefits from social support at low levels of stress, but social support provided no protection against depression and anxiety at average or high levels of stress. For nonvictims, social support provided no benefits at low levels of stress, but protected against depression and anxiety at moderate levels of stress and against depression at high levels of stress. Implications of these findings for research, theory, and intervention are discussed.     

The effect of divided attention on false memory depends on how memory is tested

In three experiments, we investigated the effects of divided attention on false memory, using the Deese/Roediger-McDermott (DRM) paradigm. In Experiments 1 and 2, participants studied six DRM lists with full attention and six in one of two divided-attention conditions (random number generation or digit monitoring). Both divided-attention conditions increased false recall of related words (Experiment 1) but reduced false recognition (Experiment 2). These results were confirmed in Experiment 3, in which the type of secondary task was manipulated within groups. We argue that the increase in false recall with divided attention reflects a change in participants' response criterion, whereas the decrease in false recognition occurs because the secondary tasks prevent participants from generating associates of the words presented at study.     

Differential effects of muscarinic receptor blockade in prelimbic cortex on acquisition and memory formation of an odor-reward task

The present experiments determined the consequences of blocking muscarinic cholinergic receptors of the prelimbic (PL) cortex in the acquisition and retention of an odor-reward associative task. Rats underwent a training test (five trials) and a 24-h retention test (two retention trials and two relearning trials). In the first experiment, rats were bilaterally infused with scopolamine (20 or 5 microg/site) prior to training. Although scopolamine rats showed acquisition equivalent to PBS-injected controls, they exhibited weakened performance in the 24-h retention test measured by number of errors. In the second experiment, rats were injected with scopolamine (20 microg/site) immediately or 1 h after training and tested 24 h later. Scopolamine rats injected immediately showed severe amnesia detected in two performance measures (errors and latencies), demonstrating deficits in retention and relearning, whereas those injected 1 h later showed good 24-h test performance, similar to controls. These results suggest that muscarinic transmission in the PL cortex is essential for early memory formation, but not for acquisition, of a rapidly learned odor discrimination task. Findings corroborate the role of acetylcholine in consolidation processes and the participation of muscarinic receptors in olfactory associative tasks.
