Using a token-actuated timer to reduce television viewing

A child watching an excessive amount of T.V. was provided a behavioral program featuring a token-actuated timer. Earned tokens were used to activate the T.V. for thirty-minute periods. The token-exchange system effectively reduced T.V. viewing and the reductions were maintained at two follow-up points. The principal contribution of the study is the development and evaluation of an electronically controlled device that was used to check the accuracy of parent-reported data.     

Recall of television commercials as a function of viewing context: the impact of program-commercial congruity on commercial messages

The effect of the congruity between the involvement types of advertising commercial and a television program on the effectiveness of the commercial was studied. Participants (N = 103) viewed either a cognitive or an affective commercial for a product, which was embedded in either a cognitive or an affective television program. The results showed that the effects of the congruence influence the impact on memory. Free recall and cued recall were significantly influenced by the program-commercial congruity. Free recall and cued recall were significantly higher for the cognitively involving commercial in the cognitively involving program context than in the affectively involving program context. Similarly, free recall and cued recall were significantly higher for the affectively involving commercial in the affectively involving program context than in the cognitively involving program context.     

Familial influences on television viewing and aggression: A sibling study

Familial influences on aggressive behavior and TV viewing were investigated in a survey of adolescent siblings. Same-sex siblings resembled one another in aggression (brothers, r = 0.59; sisters, r = 0.52) and in their exposure to violent TV programs; opposite-sex siblings were dissimilar. Within individuals, the frequency of watching crime and action programs correlated nonsignificantly with aggression. Two other variables, however, were associated with aggression: identification with aggression and aggression consequences. These relationships also held up between families (BF, covariance of sibling' averages) and within families (WF, covariance of sibling' differences). The latter WF relationship indicated that one sibling was typically the more extreme on both aggression and its correlate than a brother or sister. These results were interpreted in light of behavioral genetic data that suggest substantial genetic influences, few common environmental influences, and large within-family environmental influences on personality development.     

Self-control depletion and sleep duration: the mediating role of television viewing

Abstract

Objective: Sleep insufficiency has been related to self-control failure: people fail to go to bed in time and end up sleep deprived. The role of state self-control in predicting bedtime and sleep duration has not yet been investigated. Based on research claiming an overlap between depleted self-control resources and fatigue, self-control depletion may foster earlier bedtimes. Conversely, self-control depletion also increases the propensity to procrastinate bedtime by giving in to the immediate gratification of late night entertainment. This study therefore looked at procrastinatory television viewing and its intermediary role in the association between state self-control and bedtime. The implications for sleep duration are examined. Design: Firstyear students (N = 234) participated in an online survey. Using Day Reconstruction Method, they charted their activities and experiences during the preceding day and subsequent bedtime behavior. Results: Self-control depletion was directly related to earlier bedtimes, which we explained by its similarity to fatigue. This was associated with longer sleep duration. Self-control depletion was indirectly related to later bedtimes because it increased the propensity to procrastinate by watching television. This was associated with shorter sleep duration. Conclusion: This study exposes a dual pathway between self-control depletion and sleep duration, whereby procrastinatory television viewing may reduce sleep duration.     

Difference threshold for stimulus length under simultaneous and nonsimultaneous viewing conditions

The present study was concerned with Weber’s Law as it is related to the discriminability of the lengths of lines. Experiments were conducted to investigate three questions: (I) Is Weber’s Law equally applicable to simultaneous and nonsimultaneous viewing conditions? (2) Is the relationship between the stimulus sizes and the values ofDLs described more adequately by the function proposed by Weber or a generalized Weber’s Law stated by Miller? and (3) Is Weber’s Law better approximated by proximal or distal size? It was demonstrated that the discriminability of the lengths of lines follows Weber’s Law under the nonsimultaneous viewing condition, but not under the simultaneous viewing condition. Under the nonsimultaneous viewing condition, it was noted that the generalized Weber’s Law as stated by Miller described the relationship between the DL and stimulus size significantly better than the function proposed by Weber. From the results pertaining to the third question, it was not possible to determine whether the proximal or the distal size follows Weber’s Law more closely.     

Associations between television viewing and love styles: an interpretation using cultivation theory

This study evaluated the associations between television viewing and love styles. The Love Attitudes Scale (LAS), based on Lee's love style taxonomy, was administered to a sample of 338 unmarried Israeli students along with questions about TV viewing habits, current involvement in a serious romantic relationship, and marital intentions. A confirmatory factor analysis of the LAS indicated that the expected six-factor solution adequately fit the data. Correlations between individual love styles and TV viewing were small to moderate, ranging from .12 to .29. Scores for Ludus love style correlated positively with viewing of news and general programming. Those for Pragma love style correlated positively with news viewing and negatively with viewing genres frequently including love themes such as soap operas and family drama, while scores for Eros love style positively correlated with watching these love abundant genres. No significant association was found for TV viewing with Storge, Mania, and Agape love styles. Hierarchical regression using demographic variables, love status, and viewing habits mirrored these results, with the unique R2 for Ludus, Pragma, and Eros ranging from 1.8% to 8%, while the total variance accounted for by the models ranged from 12% to 21%. The findings can be interpreted as support for a weak cultivation effect, in which habits in long-term TV viewing among young adults correspond to small to moderate tendencies for particular love styles that thematically relate them. However, because they are correlational, the findings could equally be interpreted in terms of tendencies that exist due to modeling within families and socialization during development.     

Free viewing perceptual asymmetries for judgment of brightness and quantity: dependence on stimulus orientation

Previous research has indicated that normals exhibit strong leftward biases during free-viewing perceptual judgments of brightness and quantity. When participants view two symmetrical objects and they are forced to choose which object appears darker or more numerous, participants usually select the stimulus with the relevant feature on the left side. The present study investigated the possibility that these perceptual asymmetries are dependent on scanning a stimulus horizontally across the midline by administering a task with two rectangular reversed stimuli presented either horizontally or vertically. When the stimuli were presented horizontally (crossing the midline), participants exhibited leftward biases, but these biases disappeared when the stimuli were presented vertically. This result supports the position that free-viewing perceptual asymmetries are dependent on scanning the stimuli across the midline.     

Objective self-awareness as a nonaversive state: Effect of anticipating discrepancy reduction

The possibility that self-aware subjects in previous objective sell-awareness studies displayed heightened negative affect and avoidance reactions because they were made to focus on permanent negative discrepancies was investigated in the present research. Subjects were first induced to regard a negative real-ideal discrepancy as either permanent or reducible in size, and then were either made or not made objectively self-aware. As expected, those self-aware subjects who anticipated no reduction in discrepancy size were found to be more negative in mood and quicker to exit from the experimental room than were their counterparts in the other three conditions. It was concluded that self-focused attention only generates aversive reactions when it brings to awareness a negative real-ideal discrepancy which the individual feels cannot be altered.     

The effects of a critical television viewing curriculum on the behavior and viewing skills of emotionally disturbed adolescents in residential treatment

This study investigated the effects of training critical TV viewing skills on the subsequent attitudes and behaviors of emotionally disturbed adolescents in residential treatment. In order to test these effects, 48 institutionalized adolescents ranging from 12–18 in age, served as subjects. They were randomly assigned to one of two groups. Pre- and posttests utilized three measures of television knowledge and attitudes. Eighteen variables comprising three dependent measures were analyzed utilizing a 2 × 2 split-plots design. Training in the technical aspects of viewing proved successful in reducing susceptibility to the negative effects of the medium and provided skills that were effective in dealing with generalized aggressive behavor.     

From blooming,buzzing confusion to media literacy: The early development of television viewing

Television comprehension is a surprisingly demanding task for very young children. Based on a task analysis of television viewing and review of research, we suggest that by 6 months of age, infants can identify objects and people on screen. By 24 months they can comprehend and imitate simple actions contained in single shots and begin to integrate information across shots. Toddlers nevertheless suffer from the video deficit whereby their comprehension is less than from equivalent real life displays. During the preschool years they learn much of the grammar of filmic montage and can comprehend straightforward narrative productions. Essentially adult comprehension appears to be in place by 13 years of age.     

Depersonalization: a selective impairment of self-awareness

Depersonalization is characterised by a profound disruption of self-awareness mainly characterised by feelings of disembodiment and subjective emotional numbing. It has been proposed that depersonalization is caused by a fronto-limbic (particularly anterior insula) suppressive mechanism--presumably mediated via attention--which manifests subjectively as emotional numbing, and disables the process by which perception and cognition normally become emotionally coloured, giving rise to a subjective feeling of 'unreality'. Our functional neuroimaging and psychophysiological studies support the above model and indicate that, compared with normal and clinical controls, DPD patients show increased prefrontal activation as well as reduced activation in insula/limbic-related areas to aversive, arousing emotional stimuli. Although a putative inhibitory mechanism on emotional processing might account for the emotional numbing and characteristic perceptual detachment, it is likely, as suggested by some studies, that parietal mechanisms underpin feelings of disembodiment and lack of agency feelings.     

Right hemispheric self-awareness: a critical assessment

In this commentary I evaluate the claim made by that since self-recognition results from right hemispheric activity, self-awareness too is likely to be produced by the activity of the same hemisphere. This reasoning is based on the assumption that self-recognition represents a valid operationalization of self-awareness; I present two views that challenge this rationale. Keenan et al. also support their claim with published evidence relating brain activity and self-awareness; I closely examine their analysis of one specific review of literature and conclude that it appears to be biased. Finally, recent research suggests that inner speech (which is associated with left hemispheric activity) is linked to self-awareness-an observation that further casts doubt on the existence of a right hemispheric self-awareness.     

Airflow as a discriminative stimulus

In one experiment, pigeons were taught to discriminate airflow by having availability of reinforcement signalled by its presence and extinction signalled by its absence. After they reached criterion, some were trained on a discrimination reversal. Others were trained on an intradimensional discrimination with a low airflow velocity associated with reinforcement and a higher airflow velocity associated with extinction. All discriminations were learned rapidly, indicating that airflow velocity can function as a discriminative stimulus. In the second and third experiments, naive pigeons were trained to discriminate the presence of a compound stimulus (one of three tonal intensities paired with one of three airflow velocities) from its absence. These pigeons were subsequently given a component stimulus test during extinction on four stimulus values; the two training values, the tone alone, and the airflow alone. High or moderate velocity airflow controlled more responding than any of the three tone intensities. However, low velocity airflow controlled more responding only when a low intensity tone was employed.
