The watching eyes phenomenon: The role of a sense of being seen and public self‐awareness

In recent years, a growing number of researchers have examined the watching eyes phenomenon (i.e., increased prosocial and decreased antisocial behavior when subtle watching eyes are present in the environment). Somewhat surprisingly, the questions of how and under what conditions subtle cues of being watched operate have been unanswered so far. The present contribution addresses this research gap. In two studies, we document that (a) subtle cues of being watched induce a sense of being seen and (b) chronic public self‐awareness moderates the watching eyes phenomenon in that specifically individuals with strong chronic public self‐awareness show more prosocial behavior under conditions of watching eyes. The applicability of subtle cues of being watched in research on social presence is discussed.     

Alcohol Intoxication and Metamemory: Little Evidence that Moderate Intoxication Impairs Metacognitive Monitoring Processes

There is minimal research on metacognition in alcohol‐intoxicated participants. Study 1 examined metacognition across sober, intoxicated, and placebo groups, with the intoxicated group's breath alcohol concentration reaching 0.074 g/210 L on average immediately prior to the metacognition task. Participants answered cued recall general knowledge questions and provided confidence ratings and feeling‐of‐knowing judgments. They then completed a recognition (i.e., multiple choice) version of the same task, indicating an answer and a confidence rating for each question. Findings suggest that metacognitive accuracy generally did not vary across intoxication levels, although the control group's retrospective confidence judgments better discriminated between accurate and inaccurate responses than the alcohol groups in the recognition task. Study 2 surveyed academic psychologists about their expectations regarding the relation between alcohol and metacognition. Study 1's results were counter to their expectations, as respondents generally predicted a relation would be present. We discuss the implications for alcohol and memory.Copyright © 2017 John Wiley & Sons, Ltd.     

Social importance enhances prospective memory: evidence from an event-based task

Prospective memory performance can be enhanced by task importance, for example by promising a reward. Typically, this comes at costs in the ongoing task. However, previous research has suggested that social importance (e.g., providing a social motive) can enhance prospective memory performance without additional monitoring costs in activity-based and time-based tasks. The aim of the present study was to investigate the influence of social importance in an event-based task. We compared four conditions: social importance, promising a reward, both social importance and promising a reward, and standard prospective memory instructions (control condition). The results showed enhanced prospective memory performance for all importance conditions compared to the control condition. Although ongoing task performance was slowed in all conditions with a prospective memory task when compared to a baseline condition with no prospective memory task, additional costs occurred only when both the social importance and reward were present simultaneously. Alone, neither social importance nor promising a reward produced an additional slowing when compared to the cost in the standard (control) condition. Thus, social importance and reward can enhance event-based prospective memory at no additional cost.     

TREATMENT OF FACIAL PARALYSIS OF CNS-ORIGIN: INITIAL STUDIES

Many hemiplegic patients suffer a chronic (central) facial paralysis. Usually these patients have lost voluntary control of the involved muscles, while their ability to produce spontaneous emotional expression remains intact. Electromyographical (EMG) biofeedback and Neuro Developmental Treatment (NDT) are well-documented methods for the rehabilitation of these patients. EMG biofeedback has been described and evaluated by Huffman (1978). This technique and Huffman's findings will be briefly reviewed in the current paper. The NDT method, as well as our own pilot study, are also described. Huffman found that a combination of myofeedback and mirror-feedback led to more progress than treatment with mirror-feedback alone. From the NDT study, it is clear that improvements in orofacial functioning can be achieved. In the discussion, some principles from the neurosciences are put forward to explain the results.     

Task-specific EMG-characteristics during mental training

Despite a sixty-year tradition of research into ideomotor reaction it is not yet clear, whether myoelectric activity measured during mental training contains only inner-organismic or in addition task-specific information.Our investigation involved one group trained actively in a sensorimotor task (paced contour-tracking), another group which was intermediately instructed to train on a mental level, and a third (control) group which had no instruction for training in the intermediate performances. Measurements were taken of the muscular activity (EMG) of the main working muscle (m. biceps) synchronously to the motion of the target in all three groups.The data were submitted to several time series analysis procedures: auto-correlative measures and power spectra. Correlations were found between the filtered time series of the track and the EMG-activity in the mental training performances. The frequency distribution in the power spectra of the track was found in the power spectra of the active as well as in the mental training groups but not in those of the controls. The results indicate that the myoactivity during mental training clearly shows a task-specific frequency distribution.     

Percentage of pupillary dilation as a measure of item difficulty

The purpose of this study was to compare four measures of difficulty of mental multiplication items: percentage of pupillary dilation, latency of solution, number of correct responses, and judgment of item difficulty. Sixteen multiplication problems, classified into four levels of difficulty, were presented visually to 13 Ss, who verbalized their solutions to the problems. Analyses of variance and correlation coefficients were computed. It was concluded that all four measures of difficulty were useful but that judgment of difficulty and latency of solution were better measures of item difficulty than were the other two. A discussion of pupillary dilation and information processing is included.     

WHISTLING IN THE DARK:

Abstract— Terror management theory posits that cultural worldviews function to provide protection against anxiety concerning human vulnerability and mortality and that their effectiveness as buffers against such anxiety is maintained through a process of consensual validation. Two field experiments were conducted to test the hypothesis that incidental reminders of one's mortality increase the need to believe that others share one's worldview. In both studies, passersby on city streets were asked to estimate the extent of social consensus for culturally relevant attitudes, 100 m before passing a funeral home, 100 m after passing a funeral home, or directly in front of a funeral home. In the first study, conducted in Germany, subjects were asked to estimate the percentage of Germans who shared their opinions about a proposal to change the German constitution to restrict the immigration of foreigners, in the second study, conducted in the United Stales, subjects were asked to estimate the percentage of Americans who shared their opinions about the teaching of Christian values in the public schools. In both studies, subjects who held the minority position on the issue estimated greater consensus for their opinions when interviewed directly in front of a funeral home than when interviewed either before or after passing it.     

An automated exercise wheel for primates

Both adult and juvenile nonhuman primates can be unpredictable, difficult to handle, and potentially dangerous. Accordingly, in evaluating their activity level, they must be carefully confined. We have modified and redesigned an exercise system for primates. The exercise wheel was originally described by Curran, Wiegel, and Stevens (1972) and later adapted by Elizondo (1989). Our modifications and training procedures, which allowed us to bring the behavior of the monkey under stimulus control within 4 weeks, are described here.     

Psychophysical features of the transition from pure heat perception to heat pain perception

The psychophysical features of the transition from the pure heat to the heat pain range were studied in 25 healthy subjects (mean age 28.8 years). Thirty short heat stimuli from ?1.6° C to + 1.6° C relative to the pain threshold were applied to the thenar of the left hand with an apparatus containing a Peltier thermode (nine different temperatures at 0.4°C intervals). The subjects rated the sensation intensity on a visual analogue scale. The resulting stimulus/sensation intensity relations could be explained equally well (same goodness of fit) by a model with a power function (PF) and by a model with two linear regression lines (TLR), one for stimulus intensities below and one for those above the pain threshold and intersecting at the pain threshold. The slopes of the TLR model were significantly larger above the pain threshold than below it. The PF model produced exponents between 1.8 and 1.9. We conclude that to describe the transition area, it is sufficient to use simple linear models for both the pure heat and the heat pain ranges.
