Nonspatial attributes of stimuli can influence spatial limitations of attentional control

A wide variety of psychophysical and neurophysiological research suggests that when stimuli are very close together, they cannot be attended separately. As a consequence, they cannot be represented as individual items with specific feature information associated with them. Here we report evidence that the spatial control of attention can be modulated by nonspatial features of the stimuli (such as color and luminance). Observers shifted attention from item to item within highly dense arrays of stimuli. Performance was extremely poor when all of the items in the array were an identical gray. In contrast, performance improved when items differed in color. This finding indicates that nonspatial features, such as color, can facilitate spatial selection and suggests moreover that features can be reliably associated with particular items even when the items are densely clustered.     

Evidentiality in language and cognition

What is the relation between language and thought? Specifically, how do linguistic and conceptual representations make contact during language learning? This paper addresses these questions by investigating the acquisition of evidentiality (the linguistic encoding of information source) and its relation to children's evidential reasoning. Previous studies have hypothesized that the acquisition of evidentiality is complicated by the subtleness and abstractness of the underlying concepts; other studies have suggested that learning a language which systematically (e.g. grammatically) marks evidential categories might serve as a pacesetter for early reasoning about sources of information. We conducted experimental studies with children learning Korean (a language with evidential morphology) and English (a language without grammaticalized evidentiality) in order to test these hypotheses. Our experiments compared 3- and 4-year-old Korean children's knowledge of the semantics and discourse functions of evidential morphemes to their (non-linguistic) ability to recognize and report different types of evidential sources. They also compared Korean children's source monitoring abilities to the source monitoring abilities of English-speaking children of the same age. We found that Korean-speaking children have considerable success in producing evidential morphology but their comprehension of such morphology is very fragile. Nevertheless, young Korean speakers are able to reason successfully about sources of information in non-linguistic tasks; furthermore, their performance in these tasks is similar to that of English-speaking peers. These results support the conclusion that the acquisition of evidential expressions poses considerable problems for learners; however, these problems are not (necessarily) conceptual in nature. Our data also suggest that, contrary to relativistic expectations, children's ability to reason about sources of information proceeds along similar lines in diverse language-learning populations and is not tied to the acquisition of the linguistic markers of evidentiality in the exposure language. We discuss implications of our findings for the relationship between linguistic and conceptual representations during development.     

Spontaneously occurring mother-infant swapping and the relationships of infants with their biological and foster mothers in a captive group of lowland gorillas (Gorilla gorilla gorilla)

The present study describes spontaneously occurring infant-mother swapping and the relationships of infants with their biological and foster mothers after swapping in a captive social group of lowland gorillas (Gorilla gorilla gorilla). After infant-swapping took place between a primiparous mother with a neonate and a multiparous mother with a 10-month-old infant, the mothers provided appropriate maternal care, including nursing, to their adopted infants, but the older infant still sought refuge with its biological mother more frequently than with its foster mother. Almost 2 years later, the younger infant who was weaned by its foster mother began nursing from its biological mother; the latter subsequently weaned her adopted infant. Thereafter, the older infant who was weaned exhibited an abnormal hair-plucking behavior. These results indicate that it was psychologically stressful for the gorilla infant to quickly transfer its attachment figure from the mother to another adult female when the mother continued to remain in the group.     

Income and Satisfaction in Russia

The Russian Federation has undergone some drastic economic, social-cultural, and political changes since 1989. The income of nearly half of the population has sunk below the poverty line, which has had an enormous impact on their emotional life. In this study, the relationship between income and satisfaction in Russia was examined. Three theories – need, comparison, and personality theory – were considered. Data were drawn from the first three waves of the Russet panel study (1993–1995). Russians were a little more satisfied with their income and life when they had a higher income. A positive change in income caused an increase in income-satisfaction over a one-year period. Results also showed that there was a reciprocal relationship between income-satisfaction and life satisfaction, indicating that in addition to bottom-up effects, top-down mechanisms were also at work: life satisfaction is partly a sum of domain satisfactions, but it also reflects a more trait-like character. Furthermore, within comparison theory, social comparison had the largest effect on income-satisfaction, closely followed by income needed (person-environment fit theory), and income deserved (equity theory) with the smallest effect. The need effect of income on income-satisfaction became non-significant when controlled for these three comparison mechanisms. Correction for measurement error of relationships between the endogenous variables resulted in overall stronger effects.     

Practical Considerations for Counselors Working With Hearing Children of Deaf Parents

Counseling literature has not adequately addressed various experiences encountered by hearing children of deaf adults. Awareness and understanding of these unique experiences would better prepare counselors to work with such clients. The authors review such experiences in the context of Deaf culture and believe such a review will enable the counselor to establish more effective counseling relationships with these children and their deaf parents.     

An electrophysiological study of school-aged children with a history of failure to thrive during infancy

Sixty-five subjects, ages 8 to 12, participated in a visual electrophysiological study. Twenty-two of the subjects had received a diagnosis of nonorganic failure-to-thrive (FTT) before the age of three. The remaining 43 subjects had no history of FTT and served as Controls. IQs were obtained with the abbreviated WISC-III, and the Controls were split into two groups, LO IQ and HI IQ, to provide a LO IQ Control group with an average IQ equivalent to the FTT group. Event-related brain potentials (ERPs) were recorded from five scalp locations during a cued continuous performance task (CPT). Subjects had to press a button every time they saw the letter “X” following the letter “A” (50 targets out of 400 stimuli). During the CPT, the FTT subjects made marginally more errors of omission to targets than the LO IQ Control group and significantly more errors of omission than the HI IQ Control subjects. The groups did not differ significantly on errors of commission (false alarms) or reaction times to targets. ERP averages revealed a group difference in amplitude in a late slow wave for the 50 non-X stimuli (false targets) that followed the letter A. This difference was greatest over frontal sites, where the FTT group had a more negative going slow wave than each control group. Late frontal negativity to No Go stimuli has been linked with post-decisional processing, notably in young children. Thus, the FTT subjects may have less efficient inhibitory processes, reflected by additional late frontal activation. *** DIRECT SUPPORT *** A31BB040 00006     

The interaction of home environment features and their relation to infant competence

This investigation examined the relation between features of the home environment (HOME Scale) and domains of development (Griffiths Scales) in 6-month-olds. The sample consisted of 155 families with diverse demographic characteristics who were part of a larger study. Data were analyzed using hierarchical multiple regression. More favorable eye-hand development was associated with more availability of appropriate play materials. The interaction of appropriate play materials and maternal involvement was related to both social and hearing-speech development. For the infants who had high exposure to appropriate play materials, social and hearing-speech development was more optimal if their mothers were highly involved with them. The analyses were conducted separately for low (n = 87) and middlelhigh (n = 55) socioeconomic status groups from the sample. Partial replication of the interaction effect was present for the middle/high group, but not for the low group. Findings support the importance of examining interaction as well as additive effects of the impact of early environment for relatively large samples in which there is a diversity of experiences.     

Rural Chinese youth during the transition into adulthood: Family dynamics and psychological adjustment

Rural youth in China experience numerous challenges during their transition into adulthood. Yet, research on this transition and its relevant influential factors is rare. Through the lens of family systems theory, this study examined the impacts of family dynamics (i.e., interparental and parent–adolescent interactions) in adolescence on the psychological adjustment of youth as they transition into adulthood. Participants were 1330 youth and their mothers in rural Gansu. In 2004, mothers completed questionnaires of interparental and parent–adolescent interactions when youth were adolescents (M_age = 15.03, SD = 1.15). In 2009, youth completed questionnaires of depression and self-esteem when they were emerging adults (M_age = 20.03, SD = 1.15). Results of structural equation modelling suggested that while interparental interactions in adolescence were not associated with the psychological adjustment of youth in emerging adulthood, positive parent–adolescent interactions in adolescence predicted better psychological adjustment of youth in emerging adulthood. Furthermore, mediation analysis showed that although interparental interactions did not directly affect the psychological adjustment of youth, they were positively associated with parent–adolescent interactions, which in turn contributed to the psychological adjustment of youth. The results reveal an enduring influence of family dynamics on psychological adjustment among rural Chinese youth during the transition into adulthood.     

Transforming sex therapy: Integrating erotic potential

Abstract

The goals of conventional sex therapy are examined from a humanistic perspective. Several problems associated with these objectives, their accompanying reasoning and underlying values are highlighted. The prevailing model aims to perpetuate normative performance standards. It promotes objectification and sexual mediocrity. An alternative approach is proposed, and illustrated with clinical material. Originating in existential‐experiential psychotherapy, its goals emphasize discovery of the unknown, sexual uniqueness and diversity and integrating erotic potentials.
