Relationship between maternal aggression and maternal care in the rat

Aggression among female rats is almost entirely confined to the period of late pregnancy and lactation. Behaviorally it is similar to the aggression of males including piloerection and lateral attacks, but it differs in its function. Unlike male aggression which serves to establish a social hierarchy and a territory, i. e., is competitive, maternal aggression is protective, i. e., it serves to prevent predation of the mother's offspring. In this respect it is closely related temporally and causally to maternal care; if the offspring are removed maternal aggression wanes almost immediately–its function no longer exists! Studies on aggression by mothers, among rats, from the author's laboratory are reviewed and comparisons made with maternal care. As noted, maternal aggression and maternal care are closely related during the cycle of maternal behavior and they share a similar hormonal basis and possibly the effect of uterine stimulation, but maternal care requires prolactin and the decline of progesterone while maternal aggression appears independent of pituitary hormones and does not require a decline in progesterone. Maternal aggression like maternal care appears to be organized into a hormonal phase, during pregnancy, parturition, and for about a week postpartum and a nonhormonal phase thereafter. Bilateral radiofrequency lesions of the lateral midbrain peripeduncular nucleus (PPN) produce deficits in maternal aggression if made on lactation day 7 (L7), but not earlier, without producing significant deficits in maternal behavior. Experiments showed that the PPN does not mediate hormonally stimulated maternal aggression; it appears to mediate only nonhormonally stimulated maternal aggression. Studies on the role of pregnancy hormones on long-term retention of maternal aggression and the role of olfaction in maternal aggression are also reviewed. © 1994 Wiley-Liss, Inc.     

Anxiety,hormonal responses,and coping during a judo competition

Competitive situations induced hormonal changes, depending on the outcome, victory or defeat. This study aimed to investigate the salivary testosterone (T) and cortisol (C) and the mental state responses to a real judo championship. Data about individuals’ anxiety levels, strategies of coping, and patterns of behavior were thus collected. The relationship between hormonal changes and psychological variables were also analyzed. Our results showed a C response to competition, which was especially characterized by an anticipatory rise. Depending on outcome, results did not show statistically significant different C responses. The T values noted after the last fight were significantly greater in the losers than those obtained in the winners. Hormonal response did not show a relationship with psychological variables depending on the outcome. Losers showed just before the first fight an elevated cognitive anxiety, accompanied by low self‐confidence. Moreover, they were characterized by type B behavior. Types of coping strategies also differentiated losers from winners. Finally, even if no relationships between hormonal and psychological variables depending on the outcome were found, our results showed that state and trait psychological variables, as well as the coping strategies, must be taken into account to better understand the response to competitive situations.

Knowing what a novel word is not: Two-year-olds 'listen through' ambiguous adjectives in fluent speech

Three studies investigated how 24-month-olds and adults resolve temporary ambiguity in fluent speech when encountering prenominal adjectives potentially interpretable as nouns. Children were tested in a looking-while-listening procedure to monitor the time course of speech processing. In Experiment 1, the familiar and unfamiliar adjectives preceding familiar target nouns were accented or deaccented. Target word recognition was disrupted only when lexically ambiguous adjectives were accented like nouns. Experiment 2 measured the extent of interference experienced by children when interpreting prenominal words as nouns. In Experiment 3, adults used prosodic cues to identify the form class of adjective/noun homophones in string-identical sentences before the ambiguous words were fully spoken. Results show that children and adults use prosody in conjunction with lexical and distributional cues to ‘listen through’ prenominal adjectives, avoiding costly misinterpretation.     

Eye movements and spoken language comprehension: effects of visual context on syntactic ambiguity resolution

When participants follow spoken instructions to pick up and move objects in a visual workspace, their eye movements to the objects are closely time-locked to referential expressions in the instructions. Two experiments used this methodology to investigate the processing of the temporary ambiguities that arise because spoken language unfolds over time. Experiment 1 examined the processing of sentences with a temporarily ambiguous prepositional phrase (e.g., "Put the apple on the towel in the box") using visual contexts that supported either the normally preferred initial interpretation (the apple should be put on the towel) or the less-preferred interpretation (the apple is already on the towel and should be put in the box). Eye movement patterns clearly established that the initial interpretation of the ambiguous phrase was the one consistent with the context. Experiment 2 replicated these results using prerecorded digitized speech to eliminate any possibility of prosodic differences across conditions or experimenter demand. Overall, the findings are consistent with a broad theoretical framework in which real-time language comprehension immediately takes into account a rich array of relevant nonlinguistic context.     

Combined Individual/Marital Therapy: A Conflict Resolution Framework and Ethical Considerations

This paper illustrates how couple and individual treatment formats can be intertwined. A conflict resolution theoretical framework structures treatment around three goals: (1) relieving symptoms (anger, depression, and marital distress), (2) facilitating resolution of the couple's conflicts, and (3) building communication and conflict resolution skills. The literature review focuses on why combining individual and couple therapy is often important for married clients. Two Bicycles, an illustrative case incorporating both conjoint and individual interventions, is presented and analyzed with regard to when each format seems beneficial. Ethical and practical issues raised by dual format treatment include potential harm, informed consent, dual roles, confidentiality, and time and financial costs.     

Putting Emotional Reactivity in its Place? Exploring Family-of-origin Influences on Emotional Reactivity,Conflict, and Satisfaction in Premarital Couples

The purpose of this research was to develop a structural equation model that tested the effects of emotional reactivity on the relational health of a representative sample of 736 premarital couples. We hypothesized that partners’ perceived family-of-origin experience would be predictive of partners’ reports of their own and their partners’ emotional reactivity. These reports were hypothesized to predict partners’ reports of their own and their partners’ ability to manage conflict, which were hypothesized to predict relationship satisfaction. Overall, the model fit the data quite well, with particularly interesting differences by gender. We discuss the model’s fit within the larger body of literature, the potential implications and limitations of our findings, and future research considerations.

The transition from therapist to executive coach

A growing number of clinicians are making the transition from therapist to executive coach. High-powered executives are exceptionally receptive to the very straightforward and pragmatic approach of REBT. However, to be successful, even a REBT trained clinician had best adapt his approach to the executive client. The primary focus needs to be on more effective and efficient job performance, not on helping the client feel better. Although these executives believe many of the same irrational beliefs as one’s clinical clients, the REBT coach can effectively illustrate how each of these beliefs contributes to specific job related problems which the executive had best resolve. Teaching executives to challenge their ideas, then assigning work-related action plans, usually results in enhanced performance, which convinces even skeptical executives that coaching is a useful endeavor. Coaching has an advantage over therapy in that the coach can observe their client in numerous work situations (meetings, presentations, performance reviews) and give constructive feedback, and actually monitor additional progress. It is an exciting field that many clinicians find extremely challenging and stimulating. Dr. William D. Criddle, MBA is a managerial psychologist and executive coach in independent practice, based in Seattle, WA, USA. He is a Fellow of the Albert Ellis Institute in New York City.

Effects of prosodically modulated sub-phonetic variation on lexical competition

Eye movements were monitored as participants followed spoken instructions to manipulate one of four objects pictured on a computer screen. Target words occurred in utterance-medial (e.g., Put the cap next to the square) or utterance-final position (e.g., Now click on the cap). Displays consisted of the target picture (e.g., a cap), a monosyllabic competitor picture (e.g., a cat), a polysyllabic competitor picture (e.g., a captain) and a distractor (e.g., a beaker). The relative proportion of fixations to the two types of competitor pictures changed as a function of the position of the target word in the utterance, demonstrating that lexical competition is modulated by prosodically conditioned phonetic variation.
