On the malleability of emotional encoding

The encoding of emotional events has sometimes been regarded as automatic, because the processing involved can occur outside awareness. However, this does not mean that emotional encoding cannot be controlled, although it may often be the case that people are unaware of how to do so, or even that such control is possible. Evidence is presented to show that the neural activation associated with fear-related stimuli can be modified by top-down control, and that related instructions can modify emotional vulnerability to stressful events. However, it is further argued that such effortful control is resource limited, and that more robust control might be achieved via repeated practice in accessing positive representations that inhibit competing negative meanings. Studies of attentional and interpretative encoding biases induced by practice show that they have causal effects on emotional vulnerability, by influencing how threatening events are encoded. Experimental investigations are beginning to reveal the critical processes underlying these changes in emotional vulnerability, and it is argued that the same approach is likely to be helpful in addressing questions relevant to therapeutic change.     

The causal role of interpretive bias in anxiety reactivity

Elevated anxiety vulnerability is associated with a tendency to interpret ambiguous stimuli as threatening, but the causal basis of this relationship has not been established. Recently, procedures have been developed to systematically manipulate interpretive bias, but the impact of such manipulation on anxiety reactivity to a subsequent stressor has not yet been examined. In the present study, training procedures were used to induce interpretive biases favoring the threatening or nonthreatening meanings of ambiguous information in a sample of 48 undergraduate students. Following this interpretive training, participants' emotional reactions to a stressful video were assessed. The finding that the manipulation of interpretive bias modified emotional reactivity supports the hypothesis that interpretive bias can indeed play a causal role in anxiety vulnerability.     

INCREASING ENGAGEMENT IN DAILY ACTIVITIES BY OLDER ADULTS WITH DEMENTIA

This study analyzed the effects of nursing assistants' use of prompts and praise to increase the engagement of older adults with dementia in daily living activities. The multiple baseline design across morning and afternoon work shifts showed consistent increases in engagement by each of the 5 residents during the intervention. These results suggest that increasing prompts and praise by nursing assistants may, in turn, increase the rate of engagement of older adults with dementia.     

DECREASING DANGEROUS INFANT BEHAVIORS THROUGH PARENT INSTRUCTION

One adult and three adolescent mothers with 1-year-old infants were taught to reduce their infants' potential for injury in the home. After being taught to increase their positive interactions with their infants, the mothers were taught to child-proof the home, to use playpen time-out for potentially dangerous behaviors, and to give positive attention for safe behaviors. A multiple baseline design across subjects was used to evaluate functional control. Potentially dangerous behaviors, observed during 10 min of free play, decreased from variable and, at times, high rates during baseline to stable near-zero rates after treatment. These target behaviors remained low at a 7-month follow-up assessment.     

Behavior analysis and public policy

The Task Force on Public Policy was created to examine ways for behavior analysts to be more functional citizen scientists in the policymaking arena. This report informs readers about the contexts and processes of policymaking; and it outlines issues regarding the roles of behavior analysts in crating policy-relevant conceptual analyses, generating research data, and communicating policy-relevant information. We also discuss a possible role for the professional association in enhancing analysis, research, and advocacy on policies relevant to the public interest.     

Educational Background,Marital Status,Moral Obligation,and the Nurse's Decision to Resign from Her Hospital1

Based on the theory of reasoned action, the present research built separate models of turnover for baccalaureate and nonbaccalaureate nurses and for married and unmarried ones. A representative sample of 755 registered nurses completed the research questionnaire. Six months later, information was obtained from their hospitals concerning whether each nurse remained or resigned. Results were supportive of the theory of reasoned action. Furthermore, significant differences emerged in the predictors for the four subgroups. Moral obligation was found to be a significant predictor for intention only for baccalaureate and unmarried nurses. Part-time versus full-time employment status was found to be a significant predictor of turnover only for unmarried nurses. These results indicate that individuals interested in understanding and reducing nurse turnover may wish to be sensitive to differences between various subgroups of nurses.
