Sleep Habits May Undermine Well-Being Through the Stressor Appraisal Process

The current study examined poor sleep hygiene as a behavioral factor that may undermine psychological and social well-being. Though the connection between sleep and well-being is well documented, the mechanism by which sleep hygiene may affect well-being is currently unknown. Using the transactional model of stress as a framework, we tested a multiple mediation model (N = 307) in which sleep hygiene predicts greater psychological and social well-being through one’s perceptions of primary and secondary appraisals. Results indicated mediation effects for both models; hassle appraisals and psychological strain fully mediated the relationship between sleep hygiene and well-being. These results suggest that well-being may be affected by sleep through the cognitive appraisal process.     

La diferenciación masculino-femenino: Un mito y una realidad

Resumen

El artículo se propone realizar un estudio teórico acerca de las repercusiones psíquicas y sociales de la diferenciación sexual, tomando como marco de referencia la interpretación dada por la perspectiva cognitiva a partir del concepto de «esquema basado en la dicotomía del género».

El enfoque cognitivo destaca la importancia que ejerce la identificación psico-sexual en la adquisición y desarrollo de las ideas de «masculinidad» y «femineidad». Este proceso de partición del mundo en dos clases sexuales diferenciadas ha resultado doblemente pernicioso tanto para varones como para mujeres, empobreciendo, por un lado, el desarrollo global de la personalidad e impidiendo, por otro, el entendimiento entre sus respectivas visiones del mundo.     

Exploring the relationship between retrieval disruption from collaboration and recall

When people recall together in a collaborative group they recall less than their potential. This phenomenon of collaborative inhibition is explained in terms of retrieval disruption. However, collaborative recall also re-exposes individuals to items recalled by others that they themselves might otherwise have forgotten. This re-exposure produces post-collaborative benefits in individual recall. The current study examined whether reduced retrieval disruption during group recall is related not only to less collaborative inhibition, but also to greater post-collaborative recall benefits. To test this we devised a paradigm to calculate the extent to which each individual experienced retrieval disruption during group recall. We also included two types of collaborative groups, one of which was expected to experience greater retrieval disruption than the other. Results suggest that the relationship between retrieval disruption and recall performance depends on the level at which retrieval disruption is measured. When retrieval disruption was assessed at the individual level, then minimising retrieval disruption was associated with higher recall (i.e., less collaborative inhibition and greater post-collaborative individual recall). However, when retrieval disruption was assessed at the group level there was no relationship with recall. Furthermore, the findings from this design suggest a role of cross-cueing in modulating group recall levels.     

Memantine ameliorates scopolamine-induced amnesia in chicks trained on taste-avoidance learning

In day-old chicks trained on the one-trial taste-avoidance task, activation of NMDA receptors by glutamate is particularly important in the initial stages of memory consolidation. In addition, acetylcholine receptor activation has been shown to be a necessary component of memory formation for this task because injection of scopolamine produces amnesia. Memantine, a non-competitive NMDA receptor antagonist, improves memory formation under certain impairing circumstances, despite inhibiting the activation of NMDA receptors. The present experiments tested the hypothesis that memantine can ameliorate scopolamine-induced amnesia in day-old chicks (Gallus gallus domesticus) trained on the one-trial taste-avoidance task. Three experiments assessed the effects of scopolamine, memantine, and glutamate in this task. The results of Experiment 1 demonstrated that 50.0 mM scopolamine produces significant amnesia. In Experiment 2, 1.0 mM memantine reversed the scopolamine-induced amnesia, while other doses were ineffective. In Experiment 3, injection of 50.0 mM glutamate in combination with scopolamine reversed the memantine amelioration. These results indicate a relationship between glutamate and acetylcholine in memory formation in the day-old chick.     

Dynamics of perceptual grouping: Similarities in the organization of visual and auditory groups

In vision, the Gestalt principles of perceptual organization are generally well understood and remain a subject of detailed analysis. However, the possibility for a unified theory of grouping across visual and auditory modalities remains largely unexplored. Here we present examples of auditory and visual Gestalt grouping, which share important organizational properties. In particular, similarities are revealed between grouping processes in apparent motion, auditory streaming, and static 2-D displays. Given the substantial difference in the context, within which the phenomena in question occur (auditory vs. visual, static vs. dynamic), these similarities suggest that the dynamics of perceptual organization could be associated with a common (possibly central) mechanism. If the relevance of supramodal invariants of grouping is granted, the question arises as to whether they can be studied empirically. We propose that a “force-field” theory, based on a differential-geometric interpretation of perceptual space, could provide a suitable starting point for a systematic exploration of the subjective properties of certain classes of auditory and visual grouping phenomena.     

Cognition and self-control: Cognitive control of painful sensory input

Eighty Ss were first tested for base-level response to a pain-producing stimulus and then were re-tested on the same pain stimulus after receiving 1 of 8 experimental treatments. The 8 treatments were arranged in a 2×2×2 factorial design: presence or absence of hypnotic induction procedure; presence or absence of instructions for anesthesia; and presence or absence of demands for honest reports. Neither the hypnotic-induction procedure nor the demands for honesty affected the Ss’ reports of the degree of pain experienced. The anesthesia instructions—“think of the hand as numb and insensitive as if it were a piece of rubber...”— produced an equal degree of pain reduction in hypnotic and non-hypnotic Ss and in Ss who were and those who were not exposed to demands for honesty. The results indicate that (a) Ss’ reports of pain are less affected by demands for honesty and are more closely related to their actual experiences than has been previously assumed and (b) instructions which direct Ss to exercise cognitive control over painful sensory input are effective (with or without ‘hypnosis’) in reducing the experience of pain.     

Bringing forth spirituality dialogues in family therapy education

Our intention in the following article is to bring forth connections with spiritual resources in teaching and supervision. We construct this focus within a collaborative learning approach. Methods and techniques used include curiosity, reflexivity inquiry, deconstruction, outsider witness practices and re‐authoring conversations. We evaluate how the dialogue has transformed our abilities to relate to spirituality.     

Early adolescent peer orientation and adjustment during high school

The long-term consequences of early adolescents' orientation toward peers for their adjustment during high school were assessed. Approximately 1,200 adolescents completed questionnaires in the 7th grade and in the 10th or 12th grades; course grades were also obtained from the students' school records. Early adolescents who were willing to sacrifice their talents, school performance, and parents' rules engaged in greater problem behavior and evidenced lower academic achievement than did other adolescents during high school. The poorer adjustment of adolescents with this extreme orientation toward peers was mediated by their reported involvement in deviant peer groups. In contrast, a tendency to seek advice from peers more than from parents during early adolescence had little implication for later adjustment. Discussion focuses on the need to consider the role of peer dependence along with the effects of supportive friendships during adolescence.
