Review of Book: Technology,Social Change and Human Behavior Influence for Impact. (2021). Walther,C., Cham,Switzerland. Macmillan Editorial. ISBN: 978-3-030-70001-0 / ISBN: 978-3-030-70002-7 (eBook)

The huge impact of technology on people and institutions cannot be denied. More than often, this influence seems to have negative effects on them. However, the proposal of Social Change and Human Behavior Influence for impact brings some new light on this issue: What if society were to enable its members to attain their desired goals by means of the creation and use some technology that made it possible? The central argument of this book is: humankind can take a qualitative leap to nurture people’s quality of life, and thus arrive at a state of Augmented Humanity (AH), if all humans were to understand that individual well-being is the cause and consequence of collective well-being. And technology can contribute to the realization of the AH, if those who design and use it do justice to their own capacity for generosity, compassion, honesty and courage.

     

Endogenous-like orienting of visual attention in rats

This study investigated the orienting of visual attention in rats using a 3-hole nose-poke task analogous to Posner, Information processing in cognition: the Loyola Symposium, Erlbaum, Hillsdale, (1980) covert attention task for humans. The effects of non-predictive (50% valid and 50% invalid) and predictive (80% valid and 20% invalid) peripheral visual cues on reaction times and response accuracy to a target stimulus, using Stimuli-Onset Asynchronies (SOAs) varying between 200 and 1,200 ms, were investigated. The results showed shorter reaction times in valid trials relative to invalid trials for both subjects trained in the non-predictive and predictive conditions, particularly when the SOAs were 200 and 400 ms. However, the magnitude of this validity effect was significantly greater for subjects exposed to predictive cues, when the SOA was 800 ms. Subjects exposed to invalid predictive cues exhibited an increase in omission errors relative to subjects exposed to invalid non-predictive cues. In contrast, valid cues reduced the proportion of omission errors for subjects trained in the predictive condition relative to subjects trained in the non-predictive condition. These results are congruent with those usually reported for humans and indicate that, in addition to the exogenous capture of attention promoted by both predictive and non-predictive peripheral cues, rats exposed to predictive cues engaged an additional slower process equivalent to human's endogenous orienting of attention. To our knowledge, this is the first demonstration of an endogenous-like process of covert orienting of visual attention in rats.     

Associations between sociocultural pressures to be thin, body distress, and eating disorder symptomatology among Chilean adolescent girls

This study explored the relationships between perceived sociocultural pressure to fulfill the thin beauty ideal, body distress, and the presence of eating disorder symptoms. Participants were 437 Chilean adolescent girls from Arica, northern Chile, aged 13-18. Results showed significant associations between perceived pressure from social agents to be thin and the presence of disrupted eating attitudes and behavior. The perceived influence of advertising, verbal messages and social situations related to eating and dieting emerged as the strongest predictors of eating disorders symptoms. Influence of advertising was also the strongest predictor of body image distress. Age differences emerged in perceived sociocultural pressure to be thin, with older participants reporting higher sociocultural pressure to fulfill the slender beauty ideal. This paper provides information about body distress and associated disturbances, a phenomenon which has seldom been studied in non-Western countries, but which has important health implications.     

The self-image in borderline personality disorder: an in-depth qualitative research study

Patients with borderline personality disorder (BPD) suffer from affective instability, impulsivity, and identity disturbance which particularly manifest in an unstable or insecure self-image. One main problem for studies of core psychopathology in BPD is the complex subject of identity disturbance and self-image. The purpose of this study was to investigate the self-image of BPD patients with a qualitative research approach. Twelve patients with BPD were compared to 12 patients with remitted major depressive disorder (MDD) without personality disorder, using the Structured Interview of Personality Organization (STIPO). The transcribed interviews were analyzed using a combination of content analysis and grounded theory. BPD patients described themselves predominantly as helpful and sensitive; reported typical emotions were sadness, anger, and anxiety. MDD patients on the other hand reported numerous and various characteristics and emotions, including happiness, as well as sadness and anxiety. Other persons were characterized by the BPD group as egoistic and satisfied, while the MDD group described others as being balanced and secretive. BPD patients displayed an altruistic, superficial, and suffering self-image. Aggressive tendencies were only seen in other persons. Our findings support the concept of a self and relationship disturbance in BPD which is highly relevant for psychotherapy treatment.     

The effects of risk-glorifying media exposure on risk-positive cognitions, emotions, and behaviors: a meta-analytic review

In recent years, there has been a surge in the quantity of media content that glorifies risk-taking behavior, such as risky driving, extreme sports, or binge drinking. The authors conducted a meta-analysis involving more than 80,000 participants and 105 independent effect sizes to examine whether exposure to such media depictions increased their recipients' risk-taking inclinations. A positive connection was found for overall, combined risk taking (g=.41); as well as its underlying dimensions: risk-taking behaviors (g=.41), risk-positive cognitions and attitudes (g=.35), and risk-positive emotions (g=.56). This effect was observed across varying research methods (experimental, correlational, longitudinal); types of media (video games, movies, advertising, TV, music); and differing risk-related outcome measures (e.g., smoking, drinking, risky driving, sexual behavior). Multiple moderator analyses revealed 2 theoretically new boundary conditions for sociocognitive models. First, the effect was stronger for active (i.e., video games) than for passive (e.g., film, music) exposure to risk-glorifying media content. Second, the effect was stronger when there was a high degree of contextual fit between the media content and type of risk-taking measure. The theoretical, practical, and societal implications of the present research synthesis are discussed.     

Effects of syllable structure in aphasic errors: implications for a new model of speech production

Current models of word production assume that words are stored as linear sequences of phonemes which are structured into syllables only at the moment of production. This is because syllable structure is always recoverable from the sequence of phonemes. In contrast, we present theoretical and empirical evidence that syllable structure is lexically represented. Storing syllable structure would have the advantage of making representations more stable and resistant to damage. On the other hand, re-syllabifications affect only a minimal part of phonological representations and occur only in some languages and depending on speech register. Evidence for these claims comes from analyses of aphasic errors which not only respect phonotactic constraints, but also avoid transformations which move the syllabic structure of the word further away from the original structure, even when equating for segmental complexity. This is true across tasks, types of errors, and, crucially, types of patients. The same syllabic effects are shown by apraxic patients and by phonological patients who have more central difficulties in retrieving phonological representations. If syllable structure was only computed after phoneme retrieval, it would have no way to influence the errors of phonological patients. Our results have implications for psycholinguistic and computational models of language as well as for clinical and educational practices.
