The Role of Art in Emotional-Moral Reflection on Risky and Controversial Technologies: the Case of BNCI

In this article, we explore the role that art can play in ethical reflection on risky and controversial technologies. New technologies often give rise to societal controversies about their potential risks and benefits. Over the last decades, social scientists, psychologists, and philosophers have criticized quantitative approaches to risk on the grounds that they oversimplify its societal and ethical implications. There is broad consensus amongst these scholars that stakeholders and their values and concerns should be included in decision-making about technological risks. It has also been argued that the emotional responses of people can shed important light on the ethical aspects of risk and uncertainty. However, people’s emotions can be narrowly focused and biased. This article therefore assesses the role that technology-inspired artworks can play in overcoming such biases, by challenging our imagination and providing us with different perspectives on possible technological developments and their implications for society. Philosophers have not yet studied such artworks, so this constitutes an entirely new field of research for scholars of risk and moral theory. In particular, we focus on the case of BNCI (Brain/Neural Computer Interface) technologies and related artworks. These technologies and artworks touch on questions of what it means to be human, thereby raising profound ethical and philosophical challenges. We discuss the experiences of artists, scientists, and engineers who are directly involved with BNCI technologies, and who were interviewed during a Hackathon at Amsterdam’s Waag Society in June 2016. Their views are analyzed in light of philosophical and aesthetic theories, which allows us to consider relevant ethical and conceptual issues as well as topics for further investigation.     

Relationship Between Rate of Eating and Degree of Satiation

ABSTRACT

Behavioral psychologists have developed effective methods of treatment for overeating and weight control, including mealtime regulation, avoidance of taboo foods, and removal of identified precursors to the bingeing behavior. The current study sought to examine the relationship between speed of eating and levels of satiation in weight conscious individuals. Ten participants were instructed to eat at a fast and a slow rate in a within-subjects reversal design. Consuming food at a slow rate helped participants achieve satiation quicker with comparable amounts of food intake. Slow eaters were also less likely to overeat. These results suggest that slow eating may prevent excessive food consumption in weight conscious individuals, constituting an effective means of weight management.     

Superior encoding enhances recall in color-graphemic synesthesia

Synesthesia is a phenomenon in which particular stimuli, such as letters or sound, generate a secondary sensory experience in particular individuals. Reports of enhanced memory in synesthetes raise the question of its cognitive and neurological substrates. Enhanced memory in synesthetes could arise from the explicit or implicit use of a synesthetic cue to aid memory, from changes unique to the synesthete brain, or from both, depending on the task. To assess this question, we tested nine color-graphemic synesthetes using standardized neuropsychological measures that should not trigger color-graphemic synesthesia (visuo-spatial tests) and measures that should trigger color-graphemic synesthesia (verbal tasks). We found a synesthetic advantage on both types of tests, primarily in the initial encoding of information. The pattern of results adds to existing evidence of advantages in synesthetic memory, as well as provides novel evidence that synesthetes may have enhanced encoding rather than superior recall. Synesthetes learn more initially, rather than forgetting less over time.     

A qualitative inquiry of Latino immigrants' work experiences in the Midwest

Latino immigrants are the largest source of immigrant workers in the United States. In this study, 11 first-generation Latino immigrants (8 men, 3 women) living in the Midwest were interviewed about their work experiences. Interview data were analyzed using consensual qualitative research methods (Hill, Thompson, & Williams, 1997). Five domains associated with the data included work for survival and power, work for social connections, work as self-determination, work barriers in the Midwest, and access to work in the Midwest. We identify ways in which vocational psychologists can intervene to work effectively with Latino newcomers seeking employment in the United States and to support their transition into new settlement communities. Suggestions for future research with immigrant workers are discussed.     

When less is heard than meets the ear: change deafness in a telephone conversation

During a conversation, we hear the sound of the talker as well as the intended message. Traditional models of speech perception posit that acoustic details of a talker's voice are not encoded with the message whereas more recent models propose that talker identity is automatically encoded. When shadowing speech, listeners often fail to detect a change in talker identity. The present study was designed to investigate whether talker changes would be detected when listeners are actively engaged in a normal conversation, and visual information about the speaker is absent. Participants were called on the phone, and during the conversation the experimenter was surreptitiously replaced by another talker. Participants rarely noticed the change. However, when explicitly monitoring for a change, detection increased. Voice memory tests suggested that participants remembered only coarse information about both voices, rather than fine details. This suggests that although listeners are capable of change detection, voice information is not continuously monitored at a fine-grain level of acoustic representation during natural conversation and is not automatically encoded. Conversational expectations may shape the way we direct attention to voice characteristics and perceive differences in voice.     

Modification of the startle reflex in a community sample: do one or two dimensions of psychopathy underlie emotional processing?

Recent research on psychopathy has begun to explore two dimensions that possibly underlie psychopathy–one related more to emotional and interpersonal traits, and another related more to antisocial behaviors. A community sample of adults was assessed for psychopathy using Hare's (1991) Psychopathy Checklist-Revised (PCL-R). Eyeblinks elicited by startle probes were recorded while participants viewed pictures of emotionally-laden stimuli. Consistent with previous research, participants scoring high on PCL-R Factor 2 (“antisocial”) showed no affective modification of startle if they also scored high on PCL-R Factor 1 (“emotional detachment”). When the factor scores were analyzed together as continuous variables in a regression analysis, however, affective modification of startle was negatively related to Factor 1 but positively related to Factor 2. The results thus provide further support for a two-factor model of psychopathy.     

Aiming for career success: The role of learning goal orientation in mentoring relationships

Learning goal orientation of mentors and protégés was investigated as it relates to protégés’ mentoring functions received and outcomes (i.e., managerial career aspirations and career satisfaction). Data from 217 mentor-protégé dyads comprised of working professionals from a variety of industries were analyzed using multivariate analysis of covariance. Results indicated that protégés who possessed high levels of learning goal orientation similar to their mentor were associated with the highest levels of psychosocial support. These protégés also reported higher levels of career development, idealized influence, enacted managerial aspirations, desired managerial aspirations, and career satisfaction when compared to mentor-protégé dyads who possessed low levels of learning goal orientation or dyads with dissimilar levels of learning goal orientation. Implications for practice and future research are discussed.     

Long-term consolidation and retention of learning-induced tuning plasticity in the auditory cortex of the guinea pig.

The major goal of this study was to determine whether classical conditioning produces long-term neural consolidation of frequency tuning plasticity in the auditory cortex. Local field potentials (LFPs) were obtained from chronically implanted adult male Hartley guinea pigs that were divided into conditioning (n = 4) and sensitization control (n = 3) groups. Tuning functions were determined in awake subjects for average LFPs (approximately 0.4 to 36.0 kHz, -20 to 80 dB) immediately before training as well as 1 h and 1, 3, 7, and 10 days after training; sensitization subjects did not have a 10-day retention test. Conditioning consisted of a single session of 30 to 45 trials of a 6-s tone (CS, 70 dB) that was not the best frequency (BF, peak of a tuning curve), followed by a brief leg shock (US) at CS offset. Sensitization control animals received the same density of CS and US presentations unpaired. Heart rate recordings showed that the conditioning group developed conditioned bradycardia, whereas the sensitization control group did not. Local field potentials in the conditioning group, but not in the sensitization group, developed tuning plasticity. The ratio of responses to the CS frequency versus the BF were increased 1 h after training, and this increase was retained for the 10-day period of the study. Both tuning plasticity and retention were observed across stimulus levels (10-80 dB). Most noteworthy, tuning plasticity exhibited consolidation (i.e., developed greater CS-specific effects across retention periods), attaining asymptote at 3 days. The findings indicate that LFPs in the auditory cortex have three cardinal features of behavioral memory: associative tuning plasticity, long-term retention, and long-term consolidation. Potential cellular and subcellular mechanisms of LFP tuning plasticity and long-term consolidation are discussed.     

Psychological management intervention guidelines for rape survivors with post-traumatic stress disorder (PTSD): A brief exploratory systematic literature review

This exploratory systematic literature review aimed to characterise the current evidence on psychological management intervention guidelines for use with rape survivors with post-traumatic stress disorder (PTSD) symptoms. For the data searches we accessed the following electronic databases: Google Scholar, Science Direct, EBSCOhost, and PsychInfo. We utilised search terms with variations of the following key words: psychological management guidelines of PTSD*, rape survivors*. Inclusion criteria were guidelines for rape survivors with PTSD that consider referral, treatment, and preventive and health promotion in an international setting. We excluded guidelines that did not address PTSD resulting from rape in an international setting. We employed a narrative synthesis data analysis approach to integrate the evidence from across studies. Findings suggest prevalent guidelines for rape survivors with PTSD focus on cognitive behavioural therapy and other psychological management interventions in highly specialised areas and Primary Health Care (PHC) settings in international countries, but not in other countries such as South Africa. Emerging guidelines are needed for PTSD psychological management interventions in rape care clinics situated in South Africa.     

The experiences of therapists using a new client‐centred psychometric instrument,PSYCHLOPS (Psychological Outcome Profiles)

PSYCHLOPS (‘Psychological Outcome Profiles’) is a newly developed client‐generated psychometric instrument which can be used as an outcome measure. Uniquely, it asks clients to state their own problems, in their own words. As part of its validation, we used it alongside an existing measure, CORE‐OM (‘Clinical Outcomes Routine Evaluation – Outcome Measure’). Based on a qualitative methodology, we report here on the first‐hand experiences of four therapists using both instruments. The key themes that emerged from therapists’ responses were feasibility, validity and usefulness. Both questionnaires were perceived as complementing each other, the qualitative information from PSYCHLOPS balancing the quantitative information from CORE‐OM and that both could contribute to the therapist‐client interaction. The key features of PSYCHLOPS are likely to prove attractive to therapists and should increase acceptance and uptake of outcome measures.
