Automatic and controlled cognitive responses to intergroup threat as assessed using the process dissociation procedure: a study of a low-status group from China

Xiang, L. & Zhao, Y. (2012). Automatic and controlled cognitive responses to intergroup threat as assessed using the process dissociation procedure: A study of a low-status group from China. Scandinavian Journal of Psychology 53, 280-285. Explicit and implicit methods are typically employed to investigate the respective controlled and automatic cognitive responses to intergroup threat. However, these may not be "process pure" measures of automatic or controlled responses. The present study used the process dissociation procedure to investigate the relative contributions of automatic and controlled cognitive responses to intergroup threat. Following exposure to a threat/no threat manipulation, fifty Chinese rural undergraduates who were regarded as low-status group members completed a recognition memory task, in which they were asked to identify all or select "old" (previously presented) trait words relating to an urban outgroup. The results showed that compared to the non-threat group, when rural members perceived threat from an urban group, their automatic response was a decrease in favoritism for this outgroup, but was not derogative, whereas the controlled response was neither positive nor negative. These findings are inconsistent with previous research using explicit and implicit methods. The reasons for this discrepancy are discussed.     

Interrelations between maternal smoking during pregnancy,birth weight and sociodemographic factors in the prediction of early cognitive abilities

Maternal prenatal smoking, birth weight and sociodemographic factors were investigated in relation to cognitive abilities of 1544 children (aged 3.5 years) participating in the Québec Longitudinal Study of Children's Development. The Peabody Picture Vocabulary Test (PPVT) was used to assess verbal ability, the Wechsler Preschool and Primary Scale of Intelligence‐Revised (WPPSI‐R) block design test to assess visuospatial ability, and the Visually Cued Recall (VCR) task to assess short‐term memory. Prenatal smoking was related to performance on the WPPSI‐R, the PPVT, and the VCR, although it did not independently predict any cognitive ability after maternal education was taken into account. Birth weight was a more robust predictor of all outcome measures and independently predicted VCR‐performance. Birth weight interacted significantly with family income and maternal education in predicting visuospatial ability, indicating a greater influence of birth weight under relatively poor socio‐economic conditions. Parenting and family functioning mediated associations between maternal education/family income and cognitive task performance under different birth weight conditions, although there were indications for stronger effects under relatively low birth weight. We conclude that investigations of moderating and mediating effects can provide insights into which children are most at risk of cognitive impairment and might benefit most from interventions.

PREGNANT WOMEN'S RECOLLECTIONS OF EARLY MATERNAL BONDING: ASSOCIATIONS WITH MATERNAL–FETAL ATTACHMENT AND BIRTH CHOICES

Recollections of own maternal care measured by parental bonding were found to be important in the pregnant woman's construction of herself as a mother. Although these recollections were studied with regard to various variables, there is a dearth of studies associated with pregnancy and childbirth. In this cross‐sectional study, 341 pregnant women were recruited. Measures included a Sociodemographics–Obstetric History Questionnaire; the Childbirth Choices Questionnaire (H. Preis, M. Gozlan, U. Dan, & Y. Benyamini, 2018); the Parental Bonding Instrument (G. Parker, H. Tupling, & L.B. Brown, 1979); a question regarding the planned presence of the woman's mother at delivery; and the Maternal‐Fetal Attachment Scale (M.S. Cranley, 1981). Parental recollections of Care were associated with fewer natural birth choices (hence, a more “medicalized” delivery), lower maternal–fetal attachment, and a wish for the mother's mother to be present at the birth. Parental recollections of Encouragement of Behavioral Freedom in childhood were associated with more natural choices regarding childbirth. In addition, women with higher scores on the parental bonding Denial of Autonomy factor reported stronger maternal–fetal attachment. Thus, early recollections of experiences with caregivers as manifested in parental bonding may be a possible influence on the transition to motherhood, and working through possible difficulties associated with these recollections may improve adjustment to motherhood.     

Studies of operant and reflexive key pecks in the pigeon

The duration of pigeons' key pecks was studied in three experiments. Experiment I revealed that key pecks early in exposure to continuous reinforcement were of short duration, as were key pecks observed on an omission procedure in which pecks prevented food delivery. Key pecks later in exposure to continuous reinforcement, and those that occurred on positive automaintenance procedures, were of long duration. In Experiment II, pigeons were exposed to fixed-interval and fixed-ratio reinforcement schedules, and durations were recorded separately for each quarter of each interval or ratio. On fixed interval, durations were shorter in the first quarter of each interval than in subsequent quarters; on fixed ratio, durations were longer in the first quarter of the ratio than in subsequent quarters. These data parallel observations of concurrent operant responding and salivation in dogs. In Experiment III, pigeons were exposed to a discrete trial, differential-reinforcement-of-low-rate 6-sec schedule. Durations of responses in the first 2 sec of the trial were substantially shorter than those of responses that occurred later. The data from all three experiments support the view that the pigeon's "key peck" actually consists of two subclasses of peck, one reflexive and one operant.     

Rebirth fantasy and the psychoanalytic process

In this paper, Jungian and Freudian perspectives on the fantasy of rebirth are explored and a brief review of the literature on the theme is used to show how that the rebirth fantasy seems to be a universal fantasy in the human mind, connected with the experience of both destruction and creation. In the psychoanalytic process the rebirth fantasy is connected with initial hopes for a better life, but is also a vehicle for creating the analytic pair and for separating from the 'totalitarian object'. An account of clinical work with a patient is given to illustrate the mutual and parallel process of rebirth in both the patient and the therapist. For the patient, the therapy was experienced as an awakening or a birth. The therapist was initially doubtful about the patient's capacity to engage in the analytic process but his involvement and interest were 'born' during the early sessions, enabling the patient to rely on him to lead her out of the claustrophobic power of the totalitarian object.     

Body perception and meal type across age and gender on a Mediterranean island (Sardinia)

Our aim was to describe the differences in consumption of types of meal (complete/incomplete) eaten at lunch and dinner by gender in people of different age groups (children, young adults and seniors). In particular, we wanted to investigate the differences in choice of meal based on perceived weight. The study involved 516 participants, of which 156 were children (8-12y), 187 were young adults (19-30y) and 173 were elderly (65-90y). A cross-sectional analysis was carried out into the choice of meal type based on the different age groups and genders, on the three Body Mass Index categories (under, normal, overweight), on the three levels of self-perception (slim, normal and heavy) and on the degrees of perception of one’s body weight (underestimation, accurate estimation, overestimation). The food eaten was grouped into three types of daily meal: (a) incomplete, (b) complete lunch or dinner, (c) always complete. Differences emerged in the type of meal eaten according to age, gender and perceived weight. The results show gender differences in associations with meal type according to the way in which body mass is measured or perceived. The choice of complete/incomplete meal type changes according to whether real weight or perceived weight is considered.     

Free birds aren't fat: Weight gain in captured wild pigeons maintained under laboratory conditions

Nine feral pigeons, 5 from an urban setting and 4 from a rural setting, were captured and maintained for 42 days under free-feeding conditions comparable to those arranged for laboratory subjects. On average, birds increased their body weights by 17% over this period. The range of increase across birds was 9 to 30%. These findings suggest that the food deprivation arranged for laboratory pigeons, which is characteristically 80% of free-feeding weights, may in some sense be less severe than it first appears.     

Effects of electric-shock delivery on schedule-induced water intake: delay of shock, shock intensity, and body-weight loss.

In each of four experiments, schedule-induced water intake in the rat was studied under fixed-time 40-sec food delivery. Experiments I and II studied the temporal relationship between response-independent electric-shock delivery and licking. Shock was delivered under a variable-time 60-sec schedule. A lick-dependent delay was imposed so that licking and shock delivery were systematically separated in time by a minimum of 1 to 15 sec. Over a wide range of shock intensities the data failed to reveal a consistent delay-of-shock effect. Similar shock intensities led to similar reduction of water intake at each delay of shock interval. Experiments III and IV studied the effects of body-weight loss on water intake during independent shock delivery. In Experiment III, shock was delivered under variable-time 60-sec with a minimum separation between shock and licking of 5 sec. In Experiment IV, shock was delivered under variable-time 180-sec. The minimum separation between shock and licking was 10 sec. In each study, the resistance of water intake to suppression by shock delivery increased as the degree of body-weight loss increased. Schedule-induced water intake was affected more by shock when the animal was maintained at 90% of free-feeding weight than at 70%.     

Effects of diazepam on schedule-controlled and schedule-induced behavior under signaled and unsignaled shock.

Schedule-controlled lever pressing and schedule-induced licking were studied in rats under a multiple fixed-interval fixed-interval schedule of food reinforcement upon which was superimposed a multiple variable-time variable-time schedule of electric-shock delivery. Shocks were signaled in one component of the multiple schedule and unsignaled in the other. The effects of diazepam upon the suppression of behavior during the signal (conditioned suppression) and during signaled and unsignaled shock (differential suppression) were studied under several shock intensities (Experiment 1) and at increased body weight (Experiment 2). In each study, diazepam led to dose-dependent increases in the rate of pressing and licking during signaled and unsignaled shock, but had little effect on conditioned suppression. the rate-enhancing effects of diazepam depended upon the intensity of shock, nature of the response, and whether or not shocks were signaled. The data was discussed in terms of (1) implications for understanding the effects of signaled and unsignaled shock on behavior, (2) the effects of diazepam on behavior suppressed by response-independent shock, and (3) comparison between operant and schedule-induced behavior.
