Metacontrast Masking and Attention

Metacontrast masking is generally considered an effect of preattentive processes operative in early vision. Because of the growing evidence of the role of attention in other phenomena previously considered low level and preattentive, its possible role in masking was explored in three experiments in which meaningful target stimuli known to capture attention (one's own name or a happy-face icon) were compared with control stimuli identical in spatial frequency and luminance. Not only were these salient stimuli significantly more resistant to masking than the control stimuli, but when one of the meaningful stimuli served as a mask, its strength was increased relative to a less meaningful variant, documenting the strong influence of attention on masking.     

Comparison of reciprocity and discussion-type counseling for marital problems

Abstract

Reciprocity counseling had previously been found to increase reported marital happiness in a study using a within-subject design. Fifty-five couples served in the present study using a between-subjects design, additional response measures, and additional positive communication training. The reciprocity counseling provided behavioral contracting, communication training and instruction in mutual reinforcement, whereas the control procedure encouraged discussion of the problems. The reciprocity counseling produced significantly more improvement than the discussion-type counseling for the three marital adjustment measures after four sessions. The improvement was maintained during the 24 months of follow-up.     

The flexible nature of everyday reciprocity: reciprocity,helping, and relationship closeness

Empathy and generalized reciprocity in compliance with requests for help

This study examined empathy and reciprocity as explanations for why people comply with requests for help. Participants (35 male and 62 female) imagined being asked for money by a person who had locked keys in a car and then reported how likely they would he to comply with such a request, whether they had previously locked their keys in their car (empathy), and, if so, whether they had been helped (reciprocity). In support of the explanation based on empathy, people who reported previously locking their keys in their cars indicated being more likely to comply.     

Masking by combination tones and bands

Masking of a pure tone by a cubic difference tone or band generated by two pure tones or by a pure tone and a narrow band of noise as a function of the level of the masker was measured for three subjects at three ratios of f₂/f₁, 1.125, 1,2, and 1.3. The three maskers used were f₁ alone, f₁ + f₂, and f₁ + NBN (60-Hz band of noise centered at f₂). At ratio 1.125, the amounts of masking produced by f₁ alone and f₁ + NBN were not significantly different for all subjects. For ratios = 1.125 and 1.2, f₁ + f₂ produced the least masking at least in two of the subjects. f₁ + NBN was the best masker at ratios 1.2 and 1.3. These results show that the masking data on cubic difference tone at very small ratios of f₂/f₁ are not reliable due to the masking effect contributed by f₁. For higher ratios, the combination band has to be used instead of combination tone because of the interaction between the signal and the cubic difference tone. Also the divergence of the effectiveness in masking by the three maskers gives an estimation of the levels of primaries at which the cubic difference tone is generated.     

Public health, well-being and reciprocity

Public-health measures are very effective and efficient means of improving health, yet public health is either neglected by the literature or fraught with unease, mainly due to the combination of the aggregate-distributive tension with the element of compulsion. I argue that this unease can be decreased by 1) a pluralist-holistic view of health, situating the normative value of health in its effect on well-being, incorporating both the objective and subjective source of the value of health; and 2) by a rich concept of reciprocity. This article supports Martha Nussbaum's critique of social-contract thinking for placing too much weight on the scale of normal functioning and productive reciprocity, as well as Sen's distinction between well-being and agency freedom. To reach an adequate understanding of the value and goal of public health within the general setting of health care, a pluralist conception of health, well-being and reciprocity is necessary.

Self-disclosure reciprocity,liking and the deviant

Conflicting predictions were derived from social exchange theory about the role of social attraction and the reciprocity norm on mutual self-disclosure in dyadic relationships. Sixty-six female subjects were exposed to one of three levels of disclosure input: conventional-low disclosure, conventional-high disclosure, or devianthigh disclosure. In support of the reciprocity norm prediction, willingness to disclose personal information was a positive function of the amount of disclosure input from another person, regardless of the degree of liking for the initial discloser.     

Masking of and by tactile pressure stimuli

Masking of and by tactile pressure stimuli was investigated in six Ss as a function of stimulus intensity (force) and stimulus onset asynchrony. Increase in the force of the masked stimulus and decrease in the force of the masking stimulus were inversely related to the magnitude of masking, as defined by either a relative or an absolute decrease in sensitivity. The introduction of stimulus onset asynchrony produced both forward and backward masking, the latter being of somewhat larger magnitude. Comparisons are made with results obtained in visual metacontrast masking.     

Development of trust and reciprocity in adolescence

We investigate the development of two types of prosocial behavior, trust and reciprocity, as defined using a game-theoretical task that allows investigation of real-time social interaction, among 4 age groups from 9 to 25 years. By manipulating the possible outcome alternatives, we could distinguish among important determinants of trust and reciprocity that are related to the risk and benefit of trusting. The results demonstrate age-related changes in sensitivity to outcome for others from late childhood until late adolescence, with different developmental trajectories for trust and reciprocity and differential sensitivity to risk and benefit for self and others.     

Understanding others,reciprocity, and self-consciousness

The article explores the basic conceptual relationship between social cognition, intersubjectivity and self-consciousness. A much-debated recent approach to social cognition, the so-called interaction theory, is the view that the ability to perceive, understand and interpret the behavior of others relies on interaction in the sense of mutual coordination of the embodied agents involved. It will be shown that this notion of reciprocity is too weak in order to fully account for social understanding. It will be argued that the idea of reciprocity should at least in some cases be conceived of as a stance persons adopt towards each other, which in turn presupposes that they acknowledge each other as self-conscious agents. This view is inspired by an argument originally introduced by Johann Gottlieb Fichte.     

Disappearing Percepts: Evidence for Retention Failure in Metacontrast Masking

Results from a number of paradigms (including change blindness, inattentional blindness, integration over saccades, and backward masking) suggest that most of the visual information we take in is not retained, even for very short periods of time. This has led some to question whether such information is ever really perceived. We examine this issue using a variant of the classic metacontrast stimulus. When a briefly presented disk is followed by a briefly presented ring, observers may report not seeing the disk. Rather they report seeing the ring flicker as if the change in form from disk to ring is not recorded. This effect is highly dependent on the interval between the onset of the disk and the onset of the ring (the “stimulus onset asynchrony” or SOA). The maximum effect is usually found at a critical SOA of about 50 msec. Here we show that the ability of observers to distinguish such a disk/ring pair from a flickering ring is dependent also on how soon after the stimulus they respond. Early responses show a much smaller masking effect than late responses: Near the critical SOA accuracy improves when the observer responds more quickly (the opposite of the standard speed-accuracy trade-off), although at longer and shorter SOAs observers are less accurate on these early responses (a typical speed-accuracy trade-off). We interpret this finding as demonstrating that, at least in the case of metacontrast, retention of form information is disrupted, rather than initial access.
