Nostalgia and the emotional tone and content of song lyrics

Emotion and topic were manipulated in original song lyrics. Participants completed Batcho's and Holbrook's nostalgia surveys and rated 6 sets of lyrics for happiness, sadness, anger, nostalgia, meaning, liking, and relevance. Nostalgic lyrics were characterized by bittersweet reverie, loss of the past, identity, and meaning. Contrary to theories linking nostalgia to pathology, participants who scored high on Batcho's measure of personal nostalgia preferred happy lyrics, found them more meaningful, and related more closely to them. Consistent with theories relating nostalgia to social connectedness, high-nostalgia respondents preferred other-directed to solitary themes. Historical nostalgia was associated with relating more closely to sad lyrics.     

Effects of internet-based voucher reinforcement and a transdermal nicotine patch on cigarette smoking

Nicotine replacement products are commonly used to promote smoking cessation, but alternative and complementary methods may increase cessation rates. The current experiment compared the short-term effects of a transdermal nicotine patch to voucher-based reinforcement of smoking abstinence on cigarette smoking. Fourteen heavy smokers (7 men and 7 women) completed the four 5-day phases of the study: baseline, patch treatment, voucher treatment, and return to baseline. The order of the two treatment phases was counterbalanced across participants. In the patch treatment condition, participants wore a 14-mg transdermal nicotine patch every day. In the voucher treatment condition, participants received vouchers contingent on abstinence from smoking, defined as producing carbon monoxide (CO) readings of < or =4 parts per million. Participants e-mailed two video clips per day showing them breathing into a CO monitor and the resulting CO reading to clinic staff. In the voucher treatment, 24% of samples were negative, and 5% of samples were negative in the patch treatment. Results suggest that contingent vouchers were more effective than transdermal nicotine patches in promoting abstinence.     

Transferring voice effects in recognition memory from remembering to knowing

In five experiments, we investigated the effects of voice congruency (same vs. different voices at study and at test) on remembering and knowing in recognition memory. With low- and medium-frequency three- or four-syllable words, a voice congruency effect occurred only in remembering. With nonwords, voice congruency effects occurred both in remembering and in knowing. With nonwords and divided attention at study, the voice congruency effect transferred almost completely from remembering to knowing. By showing a transfer of effects from remembering to knowing as encoding became more impoverished, these findings support a distinctiveness/fluency account of remembering and knowing as well as the theory that remembering and knowing indicate retrieval of events from episodic and semantic memory systems, respectively.     

Parallel distributed processing and neuropsychology: A neural network model of Wisconsin card sorting and verbal fluency

Neural networks can be used as a tool in the explanation of neuropsychological data. Using the Hebbian Learning Rule and other such principles as competition and modifiable interlevel feedback, researchers have successfully modeled a widely used neuropsychological test, the Wisconsin Card Sorting Test. One of these models is reviewed here and extended to a qualitative analysis of how verbal fluency might be modeled, which demonstrates the importance of accounting for the attentional components of both tests. Difficulties remain in programming sequential cognitive processes within a parallel distributed processing (PDP) framework and integrating exceedingly complex neuropsychological tests such as Proverbs. PDP neural network methodology offers neuropsychologists co-validation procedures within narrowly defined areas of reliability and validity.     

Acoustic analysis in the differentiation of Parkinson's disease and major depression

In its early stages, Parkinson's disease (P.D.) may be difficult to distinguish from major depression (M.D.) leading to inappropriate management. Both illnesses are characterized by psychomotor retardation. The neurovegetative symptoms used to diagnose M.D. are not specific and in P.D. may be due to the physical illness itself. Currently, differentiation of the two disorders relies on subjective clinical observation. Improved diagnostic accuracy based on more objective data is needed. To this end, this study used computerized acoustic analysis to contrast speech patterns in P.D. and M.D. The sample consisted of 30 P.D. patients without depression or dementia, 30 patients with uncomplicated M.D., and 31 normal controls, each 60 years of age or over. Of the acoustic variables studied, M.D. patients had significantly reduced rates of speech compared with P.D. patients. The data suggest that this temporal measure of speech may be useful in the differentiation of P.D. and M.D.     

An outcome evaluation study of a psycho‐educational course in a primary care setting

Rationale: To date relatively little research has examined the effectiveness of psycho‐educational courses provided in a primary care setting to adults with mild‐to‐moderate mental health concerns. Aims: To determine whether group psycho‐education could be a viable alternative to individual counselling by (1) assessing the clinical effectiveness of an 8‐week psycho‐educational course, and (2) examining the group outcomes in comparison with individual treatment outcomes from a previous study in the same counselling service. Method: A total of 57 participants attending a psycho‐educational course provided data over a 36‐month period, using the Clinical Outcomes in Routine Evaluation – Outcome Measure (CORE‐OM) pre‐ and post‐intervention. A comparison was then made with the data of 58 previous participants of individual counselling evaluation, using the same CORE‐OM system. Results: Participants reported significantly lower levels of psychological distress after attending the course and these results are comparable to outcomes measured in the same service for individual counselling, indicating that group interventions could be considered a legitimate alternative to individual counselling, thus increasing cost effectiveness and reducing waiting times. Limitations of the study and implications for practice and further investigation are considered.
