Remembered odors and mental mixtures: tapping reservoirs of olfactory knowledge.

Five experiments explored how (a) perceived and remembered odor intensities relate to concentration; (b) odor intensities integrate in perceptual, memorial, and mentally constructed mixtures; and (c) components vary in intensity in physical versus mental mixtures. Ss estimated the magnitude of unmixed stimuli presented physically (perceptual estimation) or represented symbolically (memorial estimation). Ss also judged mixtures and their components in combinations of perceptual and memorial presentation. Power functions with similar exponents described the relations between both perceived and remembered intensity and concentration. Perceptual, memorial, and mental mixtures all followed much the same interactive rule of integration. Correspondingly, the intensities of components varied similarly in mentally constructed and physical mixtures. The results imply intensive invariance across odor perception and odor memory.     

Family therapy in israel: A review of therapy done under unusual circumstances

Major issues affecting family therapy practice in Israel are discussed. Issues making family therapy in Israel unique include historical topics such as the legacy of the Holocaust, the emergence of the family therapy movement from the cradle of the kibbutz; and more recent events such as constant wars, the specter of terrorist threat, and coping with the everyday pressures of life in Israel—stress, loss, and bereavement. Future trends in family therapy in the Israeli context include the peace process and the adjustment it requires from families living in the West Bank and the Golan Heights. The advent of peace and normalization will force family therapists to grapple with issues until now not given the attention they require by a country always on the brink of war, including family violence, feminist issues and patriarchal family orientations, single-parent families, and cultural diversity.The authors would like to acknowledge the help of Israel Charny, Yael Geron, Tzipi Glick, Ruth Malkinson, Judith Wertheimer, and Susan Zeidel.     

Gender identity and family relationships: Perspectives from incestuous fathers

The purpose of this study was to understand how incestuous fathers constructed their gender identities and family relationships and to determine how these perceptions were linked to incest. Analysis of intensive interviews with 20 incest offenders suggested that incest occurred in context of entitlement stemming from masculine gender constructions and family experiences which lead to conflicts regarding control and intimacy and a build up of failure. Case illustrations and implications for clinical practice are addressed.     

Time stamp in conditioned place avoidance can be set to different circadian phases

We have reported that the expression of conditioned place avoidance (CPA) in the golden hamster is regulated in a circadian pattern such that the preference is exhibited strongly at the circadian time of prior training but not at other circadian times [Cain, S. W., Chou, T., & Ralph, M. R. (2004a). Circadian modulation of performance on an aversion-based place learning task in hamsters. Behavioural Brain Research, 150(1–2), 201–205]. In that study, animals that were trained at a specific circadian time to discriminate between a “safe” context and one paired with foot shock, showed strong avoidance of the paired context at 24 and 48 h following the last training session, and showed no avoidance at 32 and 40 h following training. In the present study, we hypothesized that this “time stamp” effect is settable to any circadian phase. This was tested by training animals at one of two times of day (ZT13 or ZT4) and testing whether a time stamp would be observed, with avoidance occurring only when training and testing times match. Results confirmed our hypothesis, suggesting that the time stamp in the performance of learned tasks can be set to any circadian phase. Such an ability may allow animals in nature to predict the recurrence of 24 h events, regardless of the time of day the event was encountered.     

Paradoxes of qualitative research

In qualitative research paradoxes abound in research design, sampling, generalisation, ethics and the behaviour of the researcher. The ultimate paradox is that qualitative inquiry is impossible — both conceptually and practically — yet it still goes on. It must do so if the professions of counselling and psychotherapy are to advance.     

Technology and morality: Influences on public attitudes toward biotechnology

This study uses national survey data to test effects on individuals’ objections to biotechnology applied to plants and animals. We find that females and individuals who believe in the biblical story of creation have greater intrinsic moral objections to biotechnology than males and those who do not believe the creation story. We also find that the perception of personal benefit from biotechnology significantly decreases the likelihood of moral objection to both plant and animal biotechnology, and that perception of environmental risk from biotechnology significantly increases the likelihood of moral objection to both types of biotechnology. Policy issues are discussed. He has studied biotechnology, development, social change, work and industry. He currently works in the Survey Research Division at Research Triangle Institute in Research Triangle Park, North Carolina.

He has researched moral attitude and religious affects in biotechnology acceptance, environmentalism, and in relation to numerous controversial social concerns and issues.     

A Multisurface Interpersonal Circumplex Assessment of Rejection Sensitivity

Individuals high in rejection sensitivity (RS) are at risk for experiencing high levels of interpersonal distress, yet little is known about the interpersonal profiles associated with RS. This investigation examined the interpersonal problems, sensitivities, and values associated with RS in 2 samples: 763 multicultural undergraduate students (Study 1) and 365 community adults (Study 2). In Study 1, high anxious RS was associated with socially avoidant interpersonal problems, whereas low anxious RS was associated with vindictive interpersonal problems. In Study 2, we assessed both anxious and angry expectations of rejection. Circumplex profile analyses showed that the high anxious RS group reported socially avoidant interpersonal problems, sensitivities to remoteness in others, and valuing connections with others, whereas the high angry RS group reported vindictive interpersonal problems, sensitivities to submissiveness in others, and valuing detached interpersonal behavior. Low anxious RS was related to domineering interpersonal problems, sensitivity to attention-seeking behavior, and valuing detached interpersonal behavior, whereas low angry RS was related to submissive interpersonal problems, sensitivity to attention-seeking behavior, and valuing receiving approval from others. Overall, results suggest that there are distinct interpersonal profiles associated with varying levels and types of RS.     

Escape from fear: a detailed behavioral analysis of two atypical responses reinforced by CS termination

Escape from fear (EFF) is a controversial paradigm according to which animals learn to actively escape a fear-eliciting conditioned stimulus (CS) if the escape response (R-sub(e)) is paired with CS termination. Some theories posit that EFF learning is responsible for instrumental avoidance conditioning. However, EFF learning has typically been weaker than avoidance learning and difficult to reproduce. The authors examined EFF learning and memory with 2 atypical R-sub(e)s: rearing and nose-poking. The data suggest that rearing, but not nose-poking, can be learned as an instrumental EFF response. Further, EFF memory was response specific, aversively motivated, and controlled by the CS. Successful EFF learning also resulted in better long-term elimination of a passive fear reaction (freezing). Factors important for EFF experiments and theoretical considerations are discussed.     

Cesarean childbirth: Psychological implications for mothers and fathers

Home observations, ratings of interaction, and interviews were carried out in families with first-born 5-month-old infants. Comparisons were made between two groups of families differing as to whether the childbirth had been a Cesarean or vaginal delivery. Fathers whose babies had been born by Cesarean delivery reported greater involvement in child care and were rated as more responsive to infant distress. Both mothers and fathers tended to show less animation in interactions with their infants following a Cesarean delivery: mothers engaged less frequently in vigorous physical stimulation and showed less reciprocal positive affect with their infants, and fathers smiled less at their infants.     

Fathering during the infancy period: Implications of the mother's employment role

This study addressed fathers' satisfaction with their wives' employment role and fathers' participation in child care and household tasks in a middle-class sample of families with first-born infants in which the mother was either employed or a homemaker. Observations of mother, father, and infant were carried out in the home on weekday evenings when the infants were 12 months old, and parent interviews were carried out after the completion of the observations. On interview measures, fathers with homemaker wives tended to report greater satisfaction with their wives' employment role than did fathers whose wives were employed. In addition, fathers with employed wives, but not those with homemaker wives, reported that they were participating more in child care and household tasks as a result of their wives' emplovment role. On home observation measures, fathers with employed wives were found to engage in somewhat less Distal Interaction with their infants, but the two groups did not differ with regard to Proximal, Complex Social, or Caregiving Interactions. The results indicate the need to give special consideration to the infancy period when one is examining both paternal endorsement of maternal employment and the father's participation with children in light of the mother's employment role.
