- The aim of the study was to analyze freely generated self-presentations through the natural language processing technique of Latent Semantic Analysis (LSA). Four hundred fifty-one participants (F = 360; M = 143) recruited from LinkedIn (a professional social network) were randomly assigned to generate 10 words to describe themselves to either an employer (recruitment-condition) or a friend (friendship- condition). The words’ frequency-rate and their semantic representation were compared between condi- tions and to the natural language (Google’s n-gram database). Self-presentations produced in the recruit- ment condition (vs. natural language) had significantly higher number of agentic words (e.g., problem- solver, responsible, able team-worker) and their contents were semantically closer to the concept of agency (i.e., competence, assertiveness, decisiveness) comparing to the friendship condition. Further- more, the valence of the self-presentations’ words was higher (i.e., with a more positive meaning) in the recruitment condition. Altogether, these findings are consistent with the literature on the “Big Two,” self- presentation, and impression management.

- Background: Subjective Well-Being (SWB) is usually conceptualized in terms of an affective (i.e., judgements of biological emotional reactions and experiences) and a cognitive component (i.e., judgements of life satisfaction in relation to a psychological self-imposed ideal). Recently, researchers have suggested that judgements of harmony in life can replace or at least complement the cognitive component of SWB. Here, however, we go beyond that suggestion and propose that harmony in life should be seen as SWB’s social component since it is the sense of balance between the individual and the world around her—a process that comprises acceptance, adaptation, and balance. By adding judgements of one’s social interactions (i.e., harmony in life) to judgments of one’s life satisfaction (psycho) and judgements of one’s emotional reactions (bio), we propose a tentatively biopsychosocial model of SWB. As a first step, we used different factorial models in order to determine if both a general factor and specific sub-factors contribute to the biopsychosocial model of SWB. Method: A total of 527 participants responded to the Positive Affect Negative Affect Schedule (PANAS; 20 items), the Satisfaction with Life Scale (SWLS; five items), and the Harmony in life Scale (HILS; five items). We conducted exploratory and confirmatory factor analyses to validate the biopsychosocial model of subjective well-being and a general factor (SWBS). Results: The 20 PANAS items reflected a mixture of general latent structure saturation and specific latent structure saturation, but contributed to their respective specific latent factor (PA: 48%; NA: 49%) more than to the general latent SWBS factor (positive affect: 25%; negative affect: 32%). The five SWLS items contributed to a larger degree to the general SWBS factor (72%) than to life satisfaction itself (22%), while the five HILS items contributed to even a larger degree to the general SWBS factor (98%) than to harmony in life (0%). The bifactor model was the best model compared with all other models we tested (χ2 = 1660.78, df =375, p < .001; Satorra Bentler χ2 =1265.80, df =375, p < .001; CFI =.92; Tucker-Lewis Index =.91; RMSEA =.067). This model of a general SWBS factor explained about 64% of the total variance in the model, while specific SWBS components together explained 15% of the total variance. Conclusion: Our study suggests SWB as a general factor in a multidimensional biopsychosocial model. Indeed, as much as 64% of the variance of SWB was explained by this general factor. The SWB components, however, contributed to a different degree to each corresponding factor in the model. For instance, while the affective and cognitive components seem to be their own constructs and also part of the general SWB factor, the social component tested here contributed 0% to its own variance but 98% to the general factor.

- The physical office environment has been shown to be associated with indicators of both health and performance. This study focuses on how memory performance is affected in normal working conditions compared to a quiet baseline (with low amount irrelevant stimuli) in different office types, including cell offices, small open-plan offices, medium-sized open-plan offices and large open-plan offices. The results showed that the drop in performance from the quiet baseline to normal working conditions was higher in larger, compared to smaller, open-plan offices. However, contrary to our hypothesis we found that cell offices might have negative effects on performance comparable to those of large open-plan offices. These results indicate that employees in small open-plan offices, in comparison to large, have better possibilities to conduct cognitively demanding tasks and that cell offices might not be as advantageous as previously thought.

- Frontal cortex activity in the left hemisphere during depression is reduced. Transcranial direct current stimulation (tDCS) is a non-invasive neuromodulation technique that can increase frontal cortex activity. Therapy based on tDCS and positive psychology (PP) therapy was applied improving patients’ quality of life. The present study compared three conditions participants with clinical depression; (a) tDCS therapy, (b) positive psychotherapy, and (c) combined treatment. Hamilton Depression Rating Scale (HDRS), Adult State Hope Scale and Optimism/Pessimism Scale (OPS) was used at baseline, 2 weeks, 4-weeks and 3-months follow-up. Combined condition participants showed greater reduction in depressed mood, improved hope and optimism after 4-weeks as well as during 3-months follow-up than the other conditions. The results are discussed in terms of additive or synergistic relation between tDCS and PP treatment. Future studies should (a) use larger sample-sizes, (b) include no-treatment control conditions, (c) include double-blind designs, (d) control for previous or on-going drug therapy, (d) control for previous or ongoing psychotherapy. Furthermore, future studies should aim to increase theoretical understanding by investigating whether the relation between tDCS and psychotherapy are additive or synergistic.
