The Chances for Children Teen Parent–Infant Project: Results of a pilot intervention for teen mothers and their infants in inner city high schools

Adolescent motherhood poses serious challenges to mothers, to infants, and ultimately to society, particularly if the teen mother is part of a minority population living in an urban environment. This study examines the effects of a treatment intervention targeting low‐income, high‐risk teen mothers and their infants in the context of public high schools where daycare is available onsite. Our findings confirm the initial hypothesis that mothers who received intervention would improve their interactions with their infants in the areas of responsiveness, affective availability, and directiveness. In addition, infants in the treatment group were found to increase their interest in mother, respond more positively to physical contact, and improve their general emotional tone, which the comparison infants did not. Importantly, these findings remain even within the subset of mothers who scored above the clinical cutoff for depression on the Center for Epidemiological Studies‐Depression Scale (CES‐D; L. Radloff, 1977), confirming that it is possible to improve mother–infant interaction without altering the mother's underlying depression. The implications of these findings are significant both because it is more difficult and requires more time to alter maternal depression than maternal behavior and because maternal depression has been found to have such devastating effects on infants.     

Neuroimaging evidence for agenda-dependent monitoring of different features during short-term source memory tests

A short-term source monitoring procedure with functional magnetic resonance imaging assessed neural activity when participants made judgments about the format of 1 of 4 studied items (picture, word), the encoding task performed (cost, place), or whether an item was old or new. The results support findings from long-term memory studies showing that left anterior ventrolateral prefrontal cortex (PFC) is engaged when people make source attributions about reflectively generated information (cognitive operations, conceptual features). The findings also point to a role for right lateral PFC in attention to perceptual features and/or familiarity in making source decisions. Activity in posterior regions also differed depending on what was evaluated. These results provide neuroimaging evidence for theoretical approaches emphasizing that agendas influence which features are monitored during remembering (e.g., M. K. Johnson, S. Hashtroudi, & D. S. Lindsay, 1993). They also support the hypothesis that some of the activity in left lateral PFC and posterior regions associated with remembering specific information is not unique to long-term memory but rather is associated with agenda-driven source monitoring processes common to working memory and long-term memory.     

Social experiences and daily routines of African American infants in different socioeconomic contexts

Sixty-two 3- to 4-month-old African American infants from lower, middle, and upper socioeconomic status (SES) backgrounds were each observed in naturalistic contexts for 12 hr. The social experiences of infants in the 3 groups were similar in many ways: Infants from all backgrounds slept and were vocalized to for similar amounts of time. However, infants in the upper SES families engaged in more self-play, vocalized less, fussed less, had fewer but longer naps, and fewer but longer bouts of social interaction than did infants in the middle- and lower SES families. Infants in the upper SES families also received more verbal affection and soothing responses to their fussing and crying than did the other infants, whereas infants in the lower SES families interacted more with extended kin than did infants in the upper SES families. These results underscore the need to study African American families in a variety of socioeconomic contexts because families in more advantaged circumstances may greatly differ from those who are more disadvantaged, especially in terms of reliance on extended kin as caregivers.     

Implicit sequence learning is represented by stimulus—response rules

For nearly two decades, researchers have investigated spatial sequence learning in an attempt to identify what specifically is learned during sequential tasks (e.g., stimulus order, response order, etc.). Despite extensive research, controversy remains concerning the information-processing locus of this learning effect. There are three main theories concerning the nature of spatial sequence learning, corresponding to the perceptual, motor, or response selection (i.e., central mechanisms underlying the association between stimulus and response pairs) processes required for successful task performance. The present data investigate this controversy and support the theory that stimulus—response (S—R) rules are critical for sequence learning. The results from two experiments demonstrate that sequence learning is disrupted only when the S—R rules for the task are altered. When the S—R rules remain constant or involve only a minor transformation, significant sequence learning occurs. These data implicate spatial response selection as a likely mechanism mediating spatial sequential learning.     

Treatment of elopement following a latency‐based interview‐informed,synthesized contingency analysis

Using a latency measure during a functional analysis of problem behavior increases the brevity of the assessment period and decreases risks resulting from exposure to contexts intended to evoke problem behavior. In addition, latency‐based functional analyses may be especially suitable for discrete behaviors such as elopement, which require resetting the environment after each instance of the response. We evaluated a comprehensive assessment and treatment package for the elopement of two children diagnosed with autism. We observed short latencies to elopement during the test condition of the analysis and no elopement during the control condition. We then taught the participants multiple forms of functional communication responses of increasing complexity while elopement was blocked. This was followed by the thinning of reinforcement to a terminal goal, creating a treatment package that nearly eliminated elopement and was socially validated by caregivers.     

An Exploratory Study of Neglect and Emotional Abuse in Adolescents: Classifications of Caregiver Risk Factors

Recent research has advanced exploration of developmental stage and age-related distinctions in understanding the perpetration of child maltreatment. Using longitudinal data from the National Survey of Child and Adolescent Well-being I (NSCAW-I), this exploratory study investigated heterogeneity in caregiver risks in cases of both neglect and emotional abuse of adolescents (N = 511). Using MPlus software, a person-centered data analytic strategy–latent class analysis was performed to identify distinct classes of caregiver risk factors that were associated with the reports of maltreatment among adolescents. Subsequently exploring the distinct characteristics of the classes, we examined the related demographic characteristics, child welfare system variables (e.g., type of placement status; change in placement type between waves), and youth factors such as the presence of clinical range problem behaviors (Child Behavior Checklist). Results demonstrate four distinct classes of caregiver risk factors, with a nearly even split between those who have an absence of risk factors and those who have a whole host of risk determinants. Differences between the classes regarding the duration of time in out-of-home placements between Wave 1 and Wave 3 also emerged significant.     

Dual-task interference effects on cross-modal numerical order and sound intensity judgments: the more the louder?

In the current study, cross-task interactions between number order and sound intensity judgments were assessed using a dual-task paradigm. Participants first categorized numerical sequences composed of Arabic digits as either ordered (ascending, descending) or non-ordered. Following each number sequence, participants then had to judge the intensity level of a target sound. Experiment 1 emphasized processing the two tasks independently (serial processing), while Experiments 2 and 3 emphasized processing the two tasks simultaneously (parallel processing). Cross-task interference occurred only when the task required parallel processing and was specific to ascending numerical sequences, which led to a higher proportion of louder sound intensity judgments. In Experiment 4 we examined whether this unidirectional interaction was the result of participants misattributing enhanced processing fluency experienced on ascending sequences as indicating a louder target sound. The unidirectional finding could not be entirely attributed to misattributed processing fluency, and may also be connected to experientially derived conceptual associations between ascending number sequences and greater magnitude, consistent with conceptual mapping theory.     

The relationship between cheating behavior and sensation-seeking

Academic dishonesty is a problem in academia and cheating is a problem in society at large. Sensation-seeking was proposed as a personality trait that is positively related to one’s likelihood to cheat. A sample of 105 undergraduates participated in a research activity for course credit where cheating on a trivia game to win a cash prize by taking answers from a sealed folder was an option. As anticipated, sensation-seeking predicted cheating. Consistent with previous research, males were also more likely to cheat than females. Targeted interventions are suggested as a possible remedy.     

Are some negotiators better than others? Individual differences in bargaining outcomes

The authors address the long-standing mystery of stable individual differences in negotiation performance, on which intuition and conventional wisdom have clashed with inconsistent empirical findings. The present study used the Social Relations Model to examine individual differences directly via consistency in performance across multiple negotiations and to disentangle the roles of both parties within these inherently dyadic interactions. Individual differences explained a substantial 46% of objective performance and 19% of subjective performance in a mixed-motive bargaining exercise. Previous work may have understated the influence of individual differences because conventional research designs require specific traits to be identified and measured. Exploratory analyses of a battery of traits revealed few reliable associations with consistent individual differences in objective performance-except for positive beliefs about negotiation, positive affect, and concern for one's outcome, each of which predicted better performance. Findings suggest that the field has large untapped potential to explain substantial individual differences. Limitations, areas for future research, and practical implications are discussed.     

Age and gender differences in cardiac reactivity and subjective emotion responses to emotional autobiographical memories

This research reports age and gender differences in cardiac reactivity and subjective responses to the induction of autobiographical memories related to anger, fear, sadness, and happiness. Heart rate (HR) and subjective state were assessed at baseline and after the induction of each emotion in 113 individuals (61 men, 52 women; 66% European American, 34% African American) ranging in age from 15 to 88 years (M = 50.0; SD = 20.2). Cardiac reactivity was lower in older individuals; however, for anger and fear, these age effects were significantly more pronounced for the women than the men. There were no gender differences in subjective responses, however, suggesting that the lower cardiac reactivity found among older people is dependent on gender and the specific emotion assessed.
