Mental health consultation to law enforcement: Secret Service development of a Mental Health Liaison Program

The Mental Health Liaison Program developed and used by the Secret Service is presented as a model for comprehensive, multidimensional interactions between law enforcement and mental health systems, with particular focus on assessing and preventing violent behavior. The structure of the program pairs consultants—psychologists and psychiatrists—with Secret Service field offices to provide (a) consultation regarding risk assessment and case management of individuals who threaten or display inappropriate interest in the President or other protectees; (b) training for agents on risk assessment, mental illness, and mental health care issues; and (c) liaison activities between the Secret Service and the mental health community. Practical benefits to the Secret Service are discussed to encourage more systematic use of broad based psychological and psychiatric consultation to law enforcement, with a goal of enhanced intersystem communication and collaboration. The need for program evaluation and outcome research is discussed in the context of applying the model to improve other mental health and law enforcement systems interactions. © 1998 John Wiley & Sons, Ltd.

Job demands, job resources and individual innovation at work: going beyond Karasek's model?

The job demands-control model is one of the most recognized models in occupational stress research. It has, however, provided contradictory results, and the active learning hypothesis derived from this model has been under-researched in comparison with research on the stress hypothesis. The main aim of this study is to test the Job Demands Resources Model in the prediction of individual innovation at work as an active coping strategy. Results with hierarchical multiple regression analyses provide empirical support for this model. We found a positive relationship between job demands and individual innovation in situations characterized by high job resources. Finally, we discuss the limitations and practical implications of this study.     

Maintained attitudinal changes in nursing personnel after a brief training on suicide prevention

Nursing personnel (N = 317) working at a general hospital attended a 6-hour training program on suicide prevention. They answered anonymously pre- and post-training the Suicide Behavior Attitude Questionnaire (SBAQ), which comprises 21 visual analogue scale items divided in three factorial subscales. The results indicated there were positive changes in the attitudes and these gains were significantly maintained at the 6-month follow-up evaluation. Improvement was in the Feelings and Professional Capacity subscales (ANOVA; p = 0.0001 and 0.01, respectively). There was no change on the Right to Suicide subscale. Because attitudes influence the effectiveness of health care personnel interventions, our findings may have important implications for the development of suicide prevention programs.     

Gamma oscillations distinguish true from false memories

ABSTRACT— To test whether distinct patterns of electrophysiological activity prior to a response can distinguish true from false memories, we analyzed intracranial electroencephalographic recordings while 52 patients undergoing treatment for epilepsy performed a verbal free-recall task. These analyses revealed that the same pattern of gamma-band (28–100 Hz) oscillatory activity that predicts successful memory formation at item encoding—increased gamma power in the hippocampus, prefrontal cortex, and left temporal lobe—reemerges at retrieval to distinguish correct from incorrect responses. The timing of these oscillatory effects suggests that self-cued memory retrieval begins in the hippocampus and then spreads to the cortex. Thus, retrieval of true, as compared with false, memories induces a distinct pattern of gamma oscillations, possibly reflecting recollection of contextual information associated with past experience.     

Electrophysiological evidence for cognitive control during conflict processing in visual spatial attention

Event-related potentials were measured to investigate the role of visual spatial attention mechanisms in conflict processing. We suggested that a more difficult target selection leads to stronger attentional top-down control, thereby reducing the effects of arising conflicts. This hypothesis was tested by varying the selection difficulty in a location negative priming (NP) paradigm. The difficult task resulted in prolonged responses as compared to the easy task. A behavioral NP effect was only evident in the easy task. Psychophysiologically the easy task was associated with reduced parietal N1, enhanced frontocentral N2 and N2pc components and a prolonged P3 latency for the conflict as compared to the control condition. The N2pc effect was also obvious in the difficult task. Additionally frontocentral N2 amplitudes increased and latencies of N2pc and P3 were delayed compared to the easy task. The differences at frontocentral and parietal electrodes are consistent with previous studies ascribing activity in the prefrontal and parietal cortex as the source of top-down attentional control. Thus, we propose that stronger cognitive control is involved in the difficult task, resulting in a reduced behavioral NP conflict.     

Idiomatic processing: Syntactic frozenness and subjective familiarity

Summary Four experiments are reported that investigated idiomatic processing. Two experiments collected subjects' ratings of frozenness, familiarity, and meaningfulness for a set of idioms. The ratings obtained were used to assess the contributions of these dimensions to performance in two experiments that utilized a phoneme-identification task. Ambiguous and unambiguous phoneme targets occurred as the initial sound in the final word in idiomatic and neutral carrier phrases. Subjects' phoneme identifications were biased in the labeling of ambiguous segments in that identification responses in the idiom context tended to form an idiomatic phrase, more so than those in the neutral carrier phrase. Additional correlational analyses suggested that an idiom's degree of influence on identification depended on the rated syntactic frozenness. For subjects who knew the idioms, familiarity did not account for the biasing effect of idiomatic contexts. The experiments are discussed in terms of theories of auditory word recognition and the representation of frozenness in the mental lexicon.This research was supported by NIDCD Grant R29 NS26 587 to the first author.
