Technological paternalism: On how medicine has reformed ethics and how technology can refine moral theory

The objective of this article is to investigate ethical aspects of technology through the moral term “paternalism”. The field of investigation is medicine. The reason for this is twofold. Firstly, “paternalism” has gained moral relevance through modern medicine, where physicians have been accused of behaving paternalistic and threatening patients’ autonomy. Secondly, medicine is a brilliant area to scrutinise the evaluative aspects of technology. It is argued that paternalism is a morally relevant term for the ethics of technology, but that its traditional conception is not adequate to address the challenges of modern technology. A modification towards a “technological paternalism” is necessary. That is, “technological paternalism” is a fruitful term in the ethics of technology. Moreover, it is suited to point out the deficiencies of the traditional concept of paternalism and to reform and vitalise the conception of paternalism in ethics in order to handle the challenges of technology.     

Effects of finger and mouse pointing on learning from online split-attention examples

Background

Self-management of cognitive load is a recent development in cognitive load theory. Finger pointing has been shown to be a potential self-management strategy to support learning from spatially separated, but mutually referring text and pictures (i.e., split-attention examples).

Aims

The present study aimed to extend the prior research on the pointing strategy and investigated the effects of finger pointing on learning from online split-attention examples. Moreover, we examined an alternative pointing strategy using the computer mouse, and a combination of finger pointing and computer-mouse pointing.

Sample

One-hundred and forty-five university students participated in the present study.

Method

All participants studied an online split-attention example about the human nervous system and were randomly allocated to one of four conditions: (1) pointing with the index finger, (2) pointing with the computer mouse, (3) pointing with the index finger and the computer mouse and (4) no pointing.

Results

Results confirmed our main hypothesis, indicating that finger pointing led to higher retention performance than no pointing. However, the mouse pointing strategy and the combined finger and mouse pointing strategy did not show supportive effects.

Conclusions

Finger pointing can be used as a simple and convenient self-management strategy in online learning environments. Mouse pointing may not be as effective as finger pointing.     

The potential mediating role of anxiety sensitivity in the impact of mindfulness training on anxiety and depression severity and impairment: A randomized controlled trial

The benefits of mindfulness-based interventions to alleviate anxiety and depression have been supported by many studies. Given the effectiveness of mindfulness-based interventions on anxiety and depression, the underlying mechanisms need to be explored. Using a randomized waitlist-controlled design, this study investigated whether anxiety sensitivity was a potential mechanism for the impact of mindfulness training on anxiety and depression. Participants with high psychological distress were randomly assigned to an eight-week mindfulness intervention (N = 35) or a wait-list control group (N = 34). Before and after the intervention or corresponding waitlist period, participants completed measures of anxiety and depression severity and impairment and anxiety sensitivity. Separate mixed ANOVA demonstrated significant group (intervention vs. control group) × time (pre- vs. post-test) interactions for anxiety sensitivity and overall anxiety severity and impairment and marginally significant interaction for overall depression severity and impairment. Moreover, simple mediation models showed that reductions of anxiety sensitivity from pre- to post-test mediated the impact of mindfulness training on changes in anxiety and depression severity and impairment. The findings suggest that anxiety sensitivity is a potential mechanism underlying the effect of mindfulness training on anxiety and depression, which provides a new perspective for the study of processes of change of mindfulness-based interventions.     

Who remembers best? Individual differences in memory for events that occurred in a science museum

Individual differences in memory and suggestibility were assessed in an experiment involving 1989 people who attended the Exploratorium, a science museum located in San Francisco. Subjects watched a brief film clip of an assault and later answered questions about it. Approximately half received misinformation about some critical items. Four demographic variables (gender, educational level, age, and occupation) were examined to determine their impact on memory performance. The principle of discrepancy detection predicts that, compared to individuals with a good memory, people who have poor memory to begin with will be relatively suggestible (that is susceptible to misinformation). Some of our findings were consistent with this principle. For example, children (5–10 years) and elderly (over 65) were relatively inaccurate and also relatively suggestible. Other findings were not consistent with the principle, for example the finding that artists and architects were relatively accurate, but they were also highly suggestible.     

Job Perception–Job Satisfaction Relations: An Empirical Comparison of Three Competing Theories

Alternative conceptions of the relationship between job perceptions and job satisfaction were tested using survey responses from 450 engineers. One model, based on Job Characteristics Theory (JCT) (e.g., Hackman & Lawler, 1971), predicted that job perceptions lead to job satisfaction (JP → Sat). A second model, based on Social Information Processing (SIP) theory (e.g., Salancik & Pfeffer, 1978) and Zajonc′s (1980) theory, predicted that job satisfaction leads to job perceptions (Sat → JP). A third model, which specified a reciprocal relationship between perceptions and satisfaction (JP ↔ Sat), was developed based on James′ theory (e.g., James, Hater, Gent, & Bruni, 1978). Supervisors′ ratings of departmental characteristics were used as contextual variables along with individual difference measures as antecedents of job perceptions and job satisfaction. Model contrasts performed using LISREL VII yielded clear support for the reciprocal model based on James′ theory, in contrast to the unidirectional models based on JCT and on SIP and Zajonc′s theory. The magnitudes of the two reciprocal paths linking job perceptions and job satisfaction did not differ significantly. Directions for future research and application were offered.     

NIGHT VISION AS CHROMATIC VISION

Assuming that night vision is an exclusive function of the rods, and that it is colorless, the duplicity theory states that rod vision is achromatic vision. Studies relevant to color in night vision are reviewed. It is concluded that color may be observed well below the breakpoint of the dark adaptation curve, and that the duplicity theory therefore needs revision.     

I’m Not Feeling It: Momentary Experiential Avoidance and Social Anxiety Among Individuals With Social Anxiety Disorder

Previous studies have found that social anxiety and experiential avoidance (EA) are significantly associated, but the directionality of this relationship has not been firmly established. The present study examined momentary EA and social anxiety using repeated measurements during an opposite-sex interaction. Participants were 164 individuals (50% female): 42 were diagnosed with social anxiety disorder (SAD) and the remaining 122 were non-socially-anxious individuals (NSAs). Participants formed 42 experimental dyads including 1 individual with SAD and 1 NSA individual, and 40 control dyads including 2 NSA individuals. Lower-level mediational modeling indicated that for individuals with SAD, a reciprocal relationship was observed in which changes in both EA and social anxiety mediated changes in each other. However, changes in EA explained approximately 89% of changes in social anxiety whereas changes in social anxiety explained approximately 52% of changes in EA throughout the interaction. For NSA individuals, only social anxiety predicted EA. These findings point to a deleterious cycle driven mostly by EA among individuals with SAD, but not NSA individuals. Findings are discussed within the context of previous empirical findings as well as acceptance and commitment therapy (ACT) and cognitive-behavioral models of psychopathology.
