Private Eyes Are Watching You: Reactions to Location Sensing Technologies

Purpose  

This study explored reactions to location sensing technologies (LSTs) which enable organizations to track the location and movements of employees, even off-site. In particular, we examined the relationships among two monitoring characteristics (i.e., purpose and control), perceptions of privacy invasion, and monitoring fairness.     

Visual context modulates potentiation of grasp types during semantic object categorization

Substantial evidence suggests that conceptual processing of manipulable objects is associated with potentiation of action. Such data have been viewed as evidence that objects are recognized via access to action features. Many objects, however, are associated with multiple actions. For example, a kitchen timer may be clenched with a power grip to move it but pinched with a precision grip to use it. The present study tested the hypothesis that action evocation during conceptual object processing is responsive to the visual scene in which objects are presented. Twenty-five healthy adults were asked to categorize object pictures presented in different naturalistic visual contexts that evoke either move- or use-related actions. Categorization judgments (natural vs. artifact) were performed by executing a move- or use-related action (clench vs. pinch) on a response device, and response times were assessed as a function of contextual congruence. Although the actions performed were irrelevant to the categorization judgment, responses were significantly faster when actions were compatible with the visual context. This compatibility effect was largely driven by faster pinch responses when objects were presented in use-compatible, as compared with move-compatible, contexts. The present study is the first to highlight the influence of visual scene on stimulus–response compatibility effects during semantic object processing. These data support the hypothesis that action evocation during conceptual object processing is biased toward context-relevant actions.     

Interpersonal synchrony increases prosocial behavior in infants

Adults who move together to a shared musical beat synchronously as opposed to asynchronously are subsequently more likely to display prosocial behaviors toward each other. The development of musical behaviors during infancy has been described previously, but the social implications of such behaviors in infancy have been little studied. In Experiment 1, each of 48 14‐month‐old infants was held by an assistant and gently bounced to music while facing the experimenter, who bounced either in‐synchrony or out‐of‐synchrony with the way the infant was bounced. The infants were then placed in a situation in which they had the opportunity to help the experimenter by handing objects to her that she had ‘accidently’ dropped. We found that 14‐month‐old infants were more likely to engage in altruistic behavior and help the experimenter after having been bounced to music in synchrony with her, compared to infants who were bounced to music asynchronously with her. The results of Experiment 2, using anti‐phase bouncing, suggest that this is due to the contingency of the synchronous movements as opposed to movement symmetry. These findings support the hypothesis that interpersonal motor synchrony might be one key component of musical engagement that encourages social bonds among group members, and suggest that this motor synchrony to music may promote the very early development of altruistic behavior.

Action matters: The role of action plans and object affordances in selection for action

In a series of three experiments requiring selection of real objects for action, we investigated whether characteristics of the planned action and/or the “affordances” of target and distractor objects affected interference caused by distractors. In all ofthe experiments, the target object was selectedon the basis of colour and was presented alone or with a distractor object. We examined the effect of type of response (button press, grasping, or pointing), object affordances (compatibility with the acting hand, affordances for grasping or pointing), and target/distractor positions (left or right) on distractor interference (reaction time differences between trials with and without distractors). Different patterns of distractor interference were associated with different motor responses. In the button-press conditions of each experiment, distractor interference was largely determined by perceptual salience (e.g., proximity to initial visual fixation). In contrast, in tasks requiring action upon the objects in the array, distractors with handles caused greater interference than those without handles, irrespective of whether the intended action was pointing or grasping. Additionally, handled distractors were relatively more salient when their affordances for grasping were strong (handle direction compatible with the acting hand) than when affordances were weak. These data suggest that attentional highlighting of specific target and distractor features is a function of intended actions.     

Temporal patterns of negative and positive behavior among nursing home residents with Alzheimer's disease

Although clinical observations suggest a late-day peak in disruptive behavior in persons with dementia, results from studies of temporal patterns of behavior are equivocal. This study used direct observation methods and systematic time sampling to examine temporal patterns of negative and positive behavior in 177 residents of 2 long-term care facilities with clinically diagnosed Alzheimer's disease (AD). The authors found small statistically significant diurnal variation in both negative and positive behavior, characterized by a curvilinear pattern with a single peak. This pattern was unaffected by seasonal differences in length of day, severity of cognitive impairment, level of behavior, or sleep disturbances. Time when behavior peaked differed by type of behavior and by facility, and there was substantial heterogeneity in behavior patterns.     

Perceived intensity effects in the octave illusion

We showed that there is an intensity aspect to the octave illusion in addition to the pitch and location aspects originally reported by Deutsch (1974). In Experiment 1, we asked participants to directly compare the stimulus giving rise to the illusion (ILLU) with one mimicking its most commonly reported percept (illusion consistent; IC) and showed that they were easily able to distinguish between the two. In Experiment 2, we demonstrated a clear difference between the perceived loudness of ILLU and IC when IC follows ILLU, but not when IC precedes ILLU. In Experiments 3 and 4, we showed that this effect depends on the alternation of high and low tones between the ears in an extended pattern. In Experiment 5, we showed that this difference in perceived loudness disappears if the interval between the ILLU and IC stimuli is sufficiently large.     

Key membership and implied harmony in Western tonal music: Developmental perspectives

In three experiments on the psychophysical measurement of pain, electrocutaneous currents were applied to the volar surface of the forearm. In the first experiment, a conventional category scaling method was compared with the rating method of signal detection. The results of both methods were analyzed in detection-theory terms to derive receiver operating characteric curves and measures of the discriminability of adjacent currents. The rating method yielded larger discriminability values than the category scale did, and that method was therefore used in the subsequent experiments to examine the effect of a topical anesthetic on discriminability. When the stimuli were applied through surface electrodes, no effect of the topical anesthetic on discriminability was found, but when the stimuli were applied to a more localized area by intradermal needle electrodes, a dose-dependent effect of the anesthetic on discriminability occurred. For this experiment, the slope of the cumulative sensitivity function increased with increasing elapsed time since the removal of the anesthetic. This result is congruent with the theory that discriminability can serve as a measure of sensitivity to painful stimuli.     

Reduced Contact Cognitive-Behavioral Interventions for Adult Depression: A Review

Depression is a highly prevalent and debilitating mental health condition. Evidence suggests that there is a widening gap between the demand for and availability of effective treatments. As such, there is a vast need for the development and dissemination of accessible and affordable treatments for depression. In the past decade, there has been a proliferation of reduced client-therapist contact protocols for depression. In this article, the authors review and compare the efficacy of reduced contact cognitive-behavioral interventions for adult depression across two degrees of therapist-client contact (i.e., no therapist-client contact versus minimal therapist-client contact interventions). The authors also discuss the methodological and theoretical limitations of this research base. The present review suggests that a) reduced contact interventions for depression can be effective in remediating the symptoms of depression; b) the effect sizes of some reduced contact protocols may approximate those reported in traditional protocols involving significantly greater client-therapist contact; and c) protocols which employ some form of client-therapist contact, on average, generate higher effect sizes than those that are purely self-help in nature. A discussion of the theoretical and applied implications of such findings, as well as areas in need of further research, is provided.     

The mediating role of state maladaptive emotion regulation in the relation between social anxiety symptoms and self-evaluation bias

Although social anxiety symptoms are robustly linked to biased self-evaluations across time, the mechanisms of this relation remain unclear. The present study tested three maladaptive emotion regulation strategies – state post-event processing, state experiential avoidance, and state expressive suppression – as potential mediators of this relation. Undergraduate participants (N?=?88; 61.4% Female) rated their social skill in an impromptu conversation task and then returned to the laboratory approximately two days later to evaluate their social skill in the conversation again. Consistent with expectations, state post-event processing and state experiential avoidance mediated the relation between social anxiety symptoms and worsening self-evaluations of social skill (controlling for research assistant evaluations), particularly for positive qualities (e.g. appeared confident, demonstrated social skill). State expressive suppression did not mediate the relation between social anxiety symptoms and changes in self-evaluation bias across time. These findings highlight the role that spontaneous, state experiential avoidance and state post-event processing may play in the relation between social anxiety symptoms and worsening self-evaluation biases of social skill across time.     

Rubber hands feel the touch of light

Two experiments involving a total of 220 subjects are reported. The experiments document that "stroking" a false hand with the bright beam of light from a laser pointer can produce tactile and thermal sensations when the hand can be seen as one's own. Overall, 66% of subjects reported somatic sensations from the light. Felt hand location was recalibrated toward the location of the false hand for those subjects who felt the light. Moreover, the proprioceptive recalibration from the laser experience was comparable to that produced by actual coordinated brushing of the false hand and of the unseen real hand after 2 min of stimulation. The illusion may be experienced on one's real hand as well. The results are discussed in terms of multisensory integration.
