Infant Contingency Learning in Different Cultural Contexts

Three‐month‐old Cameroonian Nso farmer and German middle‐class infants were compared regarding learning and retention in a computerized mobile task. Infants achieving a preset learning criterion during reinforcement were tested for immediate and long‐term retention measured in terms of an increased response rate after reinforcement and after a 24‐h delay compared with baseline. It was hypothesized that infants from both cultural communities would acquire the contingency between own motion and mobile movement, as they similarly experience contingent responses in social interactions. Nso infants were assumed to show a higher learning rate related to their advanced gross motor development, whereas German infants were expected to show a higher baseline because of culture‐typical motor handling promoting a high level of activity (i.e. lying supine). Results showed immediate and long‐term retention in infants from both cultural contexts, as well as a higher baseline for German infants. Although the learning rate was higher for Cameroonian infants, logistic regression revealed that learning was not related to gross motor development but depended on the level of baseline response. Thus, contingency learning was shown in different cultural environments, and the level of baseline activity coined by culture‐specific motor handling turned out to influence learning within the mobile task.

Unconscious processes influencing learning

This paper reviews recent experimental evidence on the active involvement of non-conscious processes in human functioning and examines the contribution of this evidence to understanding learning. The experimental concept of 'unconscious processing' is compared to the psychoanalytic notion of the 'unconscious' and some relationships between the two concepts are pointed out. The general idea stemming from experimental research is that, in parallel with what goes on at the conscious level, non-conscious dynamic processes have a very strong impact both in the process and the outcome of learning. Information, which in milliseconds is non-consciously assessed as threatening to the learner's psychological balance, may be disguised or blocked from further processing, therefore affecting the learner's educational competence. The educational material, relationship or atmosphere may provoke non-conscious emotions, attitudes and intentions, which 'inflate' cognition and can affect the individual's current processing of information in various (inhibiting or enhancing) ways. By carefully observing the points where the individual learner is blocked in the 'here and now', the teacher or therapist may deduce useful information on the issues that may unconsciously inhibit learning.     

Exploring Culture-Specific Differences in Beliefs about Causes, Kinship and the Heritability of Major Depressive Disorder: The Views of Anglo-Celtic and Chinese-Australians

The aim of this study was to explore cultural differences in causal attributions and beliefs about heritability of major depressive disorder (MDD). Face-to-face interviews with Anglo-Celtic- and Chinese-Australians community members with a family history of MDD were conducted and subjected to a rigorous qualitative analysis, using the computer software NVivo. Sixteen Anglo-Celtic-Australians and 16 Chinese-Australians were interviewed. Both groups believed that a combination of genetic and environmental factors contributed to MDD, that stress was an important cause of MDD, and that coping factors were significant moderators of the impact of stress on MDD. Both cultural groups believed that the causes of MDD affecting multiple family members included a shared family environment and a “contagion effect”, in addition to genetics. Unique to the Chinese-Australian group was the beliefs that parental pressures to exceed academically contributed to MDD; this cultural group also reported beliefs that depression was due to God’s will or alternatively fate, which in turn was related to attributions to feng shui and auspicious dates. This study documented key culture-specific differences in beliefs about causes and inheritance of MDD; such differences have major implications for clinician-patient communication about genetic risk associated with having a family history of MDD.     

Development and validation of an instrument for assessing job demands arising from accelerated change: The intensification of job demands scale (IDS)

Accelerated societal and organizational changes have placed new pressures on employees. Especially, service employees are exposed to intensified workloads, planning and decision-making, and learning demands. Despite the growing attention given to this intensification of job demands, a comprehensive measure is missing. In the present study, we developed the Intensification of Job Demands Scale (IDS) and validated it in four samples (N = 1363). Confirmatory factor analyses supported the differentiation into five subscales, namely work intensification, intensified job-related planning and decision-making demands, intensified career-related planning and decision-making demands, intensified knowledge-related learning demands, and intensified skill-related learning demands. This five-factor structure holds for both the German and the English versions of the instrument. Convergent and discriminant validity tests showed that the IDS subscales are moderately related to established measures of job demands, but at most have small correlations with negative affectivity. Providing support for the incremental validity, the IDS subscales were found to add to the prediction of burnout and job satisfaction beyond established job demands. Finally, the IDS subscales helped to identify employees who experienced changes in their work situation. In sum, the results indicate that the IDS is a valid and reliable measure to assess the intensification of job demands.     

Neuromuscular Control of Posture in the Infant and Child

This study explored the effects of vision and maturation on the characteristics of neuromuscular responses underlying balance control in both seated and standing children of five age groups (3½–5 months, 8–14 months, 2–3 years, 4–6 years, and 7–10 years). A platform was used to unexpectedly disturb the child’s balance in the anterior or posterior direction. Responses of the leg, trunk, and neck muscles were recorded using surface electromyograms.

Vision was not required for the activation of these responses in any of the age groups tested. However, comparison of muscle response latencies of standing children to posterior platform translation in the two visual conditions showed a significant reduction in latency for neck flexors in the 2- to 3-year-olds with vision removed and an increase in the total number of monosynaptic reflexes. No reduction in latency was found in the older age groups. The hypothesis of a shift from an early long latency visual dominance to a shorter latency proprioceptive one during childhood is discussed.

Postural control showed a cephalo-caudal developmental gradient with postural responses appearing first in the neck, then trunk, and finally, legs, as children developed from 3 to 14 months of age. A wide variety of response patterns was seen in the 3- to 5-month-olds, indicating that postural responses are not functional prior to experience with stabilizing the center of mass.

Attention and ageing: Measuring effects of involuntary and voluntary orienting in isolation and in combination

The cueing paradigm provides an established method for eliciting involuntary and voluntary attention shifts. Involuntary orienting is traditionally measured with non‐predictive peripheral cues and voluntary orienting with predictive central arrows. Recent studies with young adults have established that predictive central arrows trigger a combination of involuntary and voluntary orienting, raising the possibility that previous studies – including those with older adults – misinterpreted their findings with central arrow cues as isolating the effects of voluntary attention. The present experiment applied different cueing conditions that measured involuntary orienting, voluntary orienting, and involuntary and voluntary orienting in combination in older adults. The results show that past studies of voluntary orienting in older adults confound involuntary and voluntary orienting. Cueing effects in a condition that for the first time isolated voluntary orienting (predictive number cues) with older adults were significant, and comparable to effects for younger adults, demonstrating that older adults successfully utilize cues to direct their spatial attention strategically. A similar normal pattern of orienting was observed for involuntary orienting. Our study provides a methodology that can be applied effectively to isolate and investigate the effects of age on voluntary and involuntary attention.     

Two‐year‐old children but not domestic dogs understand communicative intentions without language,gestures, or gaze

Infants can see someone pointing to one of two buckets and infer that the toy they are seeking is hidden inside. Great apes do not succeed in this task, but, surprisingly, domestic dogs do. However, whether children and dogs understand these communicative acts in the same way is not yet known. To test this possibility, an experimenter did not point, look, or extend any part of her body towards either bucket, but instead lifted and shook one via a centrally pulled rope. She did this either intentionally or accidentally, and did or did not address her act to the subject using ostensive cues. Young 2‐year‐old children but not dogs understood the experimenter's act in intentional conditions. While ostensive pulling of the rope made no difference to children's success, it actually hindered dogs' performance. We conclude that while human children may be capable of inferring communicative intent from a wide variety actions, so long as these actions are performed intentionally, dogs are likely to be less flexible in this respect. Their understanding of communicative intention may be more dependent upon bodily markers of communicative intent, including gaze, orientation, extended limbs, and vocalizations. This may be because humans have come under selective pressure to develop skills for communicating with absent interlocutors – where bodily co‐presence is not possible.
