Induction when rats lick for 1% liquid-sucrose reinforcement

Previous research reported that rats responding for 1% liquid-sucrose reinforcement when 32% sucrose reinforcement is upcoming will decrease their response rate (contrast) if licking is the dependent measure and increase their response rate (induction) if pressing a lever is the dependent measure. The present study investigated whether induction could be observed when licking served as the dependent measure and whether induction in lever pressing and contrast in licking behaviour could be concurrently observed. Experiment 1 found induction when rats licked to earn the rewards but consumed them at a location separate from the spout licked to earn them. Experiment 2 also found induction when rats earned (and consumed) rewards by licking the same spout throughout the session. Experiment 3 separately measured instrumental lever pressing for sucrose rewards and licking the sucrose during the reward period. We found that both measures increased for 1% sucrose when 32% sucrose reinforcement was upcoming. The present results indicate that the type of response is not the sole determinant of whether contrast or induction is observed. Rather, they suggest that other procedural details, such as the location of reinforcer delivery, influence which effect is observed. The results also indicate that associative processes underlie the appearance of induction in responding for 1% sucrose.     

Children's night-time fears: an overview

Night-time fears are a normal developmental occurrence for most children. However, a small proportion of children may experience severe night-time fears of much greater intensity and duration, and typically meet diagnostic criteria for an anxiety or phobic disorder diagnosis. The content and developmental features of children's night-time fears are explored, highlighting the heterogeneous nature of nocturnal fears. Fears of this nature are probably due to an interaction of biological, environmental and cognitive-mediational factors, together with the involvement of family and operant learning processes. Clinical assessment procedures are briefly outlined, including the behavioural interview, the diagnostic interview, self-report inventories and home-monitoring on the part of parents. Family-based cognitive-behavioural treatment strategies are described. Although research findings are encouraging for the efficacy of these interventions, future studies need to utilize methodologies that allow for the identification of the specific mechanisms responsible for treatment, and improved diagnostic assessment of night fearful children.     

Assessing the Readability of Mental Health Internet Brochures for Children and Adolescents

We investigated the readability of seven mental health brochures on mental, emotional, and behavioral disorders in children that were selected from a website developed by the Center for Mental Health Services at http://www.mentalhealth.org. The reading grade levels of the brochures ranged from 11.1 to 14.8 (mean 13.23), considerably higher than the 8th grade level recommended for educational material by the U. S. Department of Education (1986). On other readability variables, assessed using the Readability Assessment Instrument (RAIN; Singh, 1994), all brochures met criterion on most variables but failed on those for new words (audience appropriateness) and print size. This is a favorable result in comparison with other studies that have assessed readability of mental health information on the Internet using the RAIN, although less so with reading grade levels.     

Personality Disorder Attributes as Supplemental Goals for Change in Interpersonal Psychotherapy

Interpersonal Psychotherapy (IPT) is a manualized, short-term (usually 12–16 sessions) based on the assumption that psychological disorders often emerge secondary to social and interpersonal problems that require active intervention to achieve symptom remission. The time-limited nature of IPT compels therapists to establish the goal of diminishing, on a weekly basis, a small number of focused interpersonal problems with a decided emphasis on proximal rather than historic conflicts and associated patterns of behavior. This strategy discourages the adoption of diffuse therapy goals and directions that have more opportunity to emerge in long-term, unstructured treatment modalities. The role of traditional personality testing in short-term therapy, when it occurs, is to identify and quantify symptom clusters that warrant attention as dependent measures in the treatment process. The role of personality factors in the genesis or maintenance of psychological disturbance is rarely addressed. The present article explores theoretical and pragmatic objections to the use of personality testing in IPT. A method is proposed for the limited but systematic incorporation of personality testing in the IPT treatment process using the Millon Clinical Multiaxial Inventory (MCMI-III). While unreasonable to expect personality transformation through short-term therapy, the partial attenuation of maladaptive behavioral, attitudinal, and emotional reactions to stressors could prove exceedingly helpful to short-term treatments such as IPT.     

Resiliency,Self-Regulation,and Reemployment After Job Loss

This study investigated self-regulation and resiliency in one's search for reemployment. Although trait-based approaches are central to many resiliency conceptualizations, recent research has found that self-regulation (affective, behavioral, and cognitive) contributes to predicting resiliency-related outcomes. We hypothesized that self-regulation would incrementally predict reemployment process outcomes, specifically the job search outcomes of psychological well-being, job search self-efficacy, and job search clarity. Results indicated that, over and above resiliency traits, behavioral and cognitive self-regulation incrementally predicted well-being and job search clarity, and cognitive self-regulation incrementally predicted job search self-efficacy. Implications for theory and continued research on resiliency in reemployment are discussed.
