Fourteen‐month‐old infants learn similar‐sounding words

Can infants, in the very first stages of word learning, use their perceptual sensitivity to the phonetics of speech while learning words? Research to date suggests that infants of 14 months cannot learn two similar‐sounding words unless there is substantial contextual support. The current experiment advances our understanding of this failure by testing whether the source of infants’ difficulty lies in the learning or testing phase. Infants were taught to associate two similar‐sounding words with two different objects, and tested using a visual choice method rather than the standard Switch task. The results reveal that 14‐month‐olds are capable of learning and mapping two similar‐sounding labels; they can apply phonetic detail in new words. The findings are discussed in relation to infants’ concurrent failure, and the developmental transition to success, in the Switch task.     

Monolingual,bilingual, trilingual: infants' language experience influences the development of a word‐learning heuristic

How infants learn new words is a fundamental puzzle in language acquisition. To guide their word learning, infants exploit systematic word‐learning heuristics that allow them to link new words to likely referents. By 17 months, infants show a tendency to associate a novel noun with a novel object rather than a familiar one, a heuristic known as disambiguation. Yet, the developmental origins of this heuristic remain unknown. We compared disambiguation in 17‐ to 18‐month‐old infants from different language backgrounds to determine whether language experience influences its development, or whether disambiguation instead emerges as a result of maturation or social experience. Monolinguals showed strong use of disambiguation, bilinguals showed marginal use, and trilinguals showed no disambiguation. The number of languages being learned, but not vocabulary size, predicted performance. The results point to a key role for language experience in the development of disambiguation, and help to distinguish among theoretical accounts of its emergence.     

Borderline Personality Traits are Associated with Poor Clinical and Psychosocial Functioning in Delinquent Boys

Borderline personality disorder (BPD) is positively associated with antisocial behavior in adolescent boys and might increase clinical and social problems. Delinquent boys (most with multiple felony adjudications; n = 239) in a residential facility who were high in number of BPD traits (assessed via the Borderline Tendency scale of the Millon Adolescent Clinical Inventory) were compared to 1,197 control offenders in the same facility while controlling for antisocial PD traits. As expected, offenders high in BPD traits had more suicidal behavior and psychopathology features and worse peer and family relations than control offenders and were higher in rates of childhood sexual and physical abuse than controls. Groups did not differ in criminal history. Results suggest that BPD traits are associated with significant problems in functioning and these traits should be identified to help curb associated problems.     

Consumption After a Diet Violation: Disinhibition or Compensation?

ABSTRACT— Previous research, restricted to the laboratory, has found that restrained eaters overeat after they violate their diet. However, there has been no evidence showing that this same process occurs outside the lab. We hypothesized that outside of this artificial setting, restrained eaters would be able to control their eating. In Study 1 , 127 participants reported hourly on their diet violations and eating over 2 days. In Study 2 , 89 participants tracked their intake for 8 days, and 50 of these participants consumed a milk shake (a diet violation) on Day 7, as part of an ostensibly unrelated study. As hypothesized, dieters did not overeat following violations of their diet in either study. These findings are in contrast with those of previous lab studies and dispel the widely held belief that diet violations lead to overeating in everyday life.     

We are not a Healthcare Business: Our Inadvertent Vow of Poverty

Psychology has been fractionated from mainstream healthcare delivery and this schism has resulted in huge costs to psychologists and our intended customers. Psychology has also been naïve economically. The authors suggest three revolutions: (1) for clinical psychology to be better integrated into the healthcare delivery system; (2) for psychologists to better understand healthcare economics and business; and (3) for psychologists to become more entrepreneurial, i.e., see needs in healthcare (such as those of the elderly, obesity, improved access and value through ehealth) and systematically fill these. We note high quality businesses help many individuals (customers, family members, employees) not typically recognized by anti-business psychologists.     

Activating children's thinking skills (ACTS): The effects of an infusion approach to teaching thinking in primary schools

Background Recent interest in the teaching of thinking skills within education has led to an increase in thinking skills packages available to schools. However many of these are not based on scientific evaluation ( DfEE, 1999 ). This paper endeavours to examine the effectiveness of one approach, that of infusion, to teaching thinking. Aims To investigate the impact of an infusion methodology, activating children's thinking skills (ACTS), on the cognitive, social, and emotional development of children in Year 4–6 in primary schools. This is a sister project to research being conducted in Northern Ireland ( McGuinness, 2006 ). Sample The study involved 404 children from 8 primary schools in one local authority. These were divided into 160 in the experimental group and 244 in the waiting list control group. Methods A quasi‐experimental design was used with pre‐, post‐, and delayed post‐tests to ascertain changes in children's cognitive abilities, self‐perceptions, and social/behavioural skills using quantitative measures. In addition qualitative techniques were used with pupils and teachers to evaluate effectiveness. Results The experimental group made significantly greater gains in cognitive ability skills over a 2 year period compared to the waiting list control. Qualitative data demonstrated a positive impact on children's social and emotional development. In addition teacher professional development was reported to be enhanced. Conclusions This research indicated that children's cognitive abilities can be developed following a 2 year period of the ACTS infusion intervention. While some positive effects were evidenced on the social and emotional development of children, further study will be necessary to examine these in more detail.     

Amnesia,rehearsal, and temporal distinctiveness models of recall

Classical amnesia involves selective memory impairment for temporally distant items in free recall (impaired primacy) together with relative preservation of memory for recency items. This abnormal serial position curve is traditionally taken as evidence for a distinction between different memory processes, with amnesia being associated with selectively impaired long-term memory. However recent accounts of normal serial position curves have emphasized the importance of rehearsal processes in giving rise to primacy effects and have suggested that a single temporal distinctiveness mechanism can account for both primacy and recency effects when rehearsal is considered. Here we explore the pattern of strategic rehearsal in a patient with very severe amnesia. When the patient’s rehearsal pattern is taken into account, a temporal distinctiveness model can account for the serial position curve in both amnesic and control free recall. The results are taken as consistent with temporal distinctiveness models of free recall, and they motivate an emphasis on rehearsal patterns in understanding amnesic deficits in free recall.     

The phonological loop unmasked? A comment on the evidence for a "perceptual-gestural" alternative

Jones et al. (Jones, Hughes, & Macken, 2006; Jones, Macken, & Nicholls, 2004) identify the interaction between phonological similarity, articulatory suppression, and stimulus presentation mode in verbal short-term memory as potentially providing important support for the phonological loop hypothesis. They find such an interaction but attribute it to "perceptual organization masquerading as phonological storage". We present data using shorter letter sequences and find clear evidence of the interaction predicted by the phonological loop hypothesis, which, unlike the evidence of Jones et al., is not limited to recency, and which provides continued support for the phonological loop hypothesis.     

Treatment Engagement: Building Therapeutic Alliance in Home-Based Treatment with Adolescents and their Families

Client engagement is an essential yet challenging ingredient in effective therapy. Engaged clients are more likely to bond with therapists and counselors, endorse treatment goals, participate to a greater degree, remain in treatment longer, and report higher levels of satisfaction. This study explored the process of engaging high-risk youth and their parents in a unique home-based family therapy intervention. Qualitative interviews were conducted with 19 families who completed family therapy sessions that included a core component aimed at increasing treatment engagement. Parents’ and youths’ perceptions of engagement suggest the importance of developing therapeutic alliance with therapists, who facilitated building a shared alliance among family members. Implications for improving client engagement are discussed within the context of alliance building with the therapist and among family members.
