The influence of chronically and temporarily accessible information on life satisfaction judgments

The authors examined the influence of temporarily and chronically accessible information on life satisfaction judgments. Meta-analyses revealed high retest-reliability of life satisfaction judgments and weak effects of the item order of domain and global satisfaction judgments. Study 1 (N=225) failed to replicate a widely cited finding of strong item-order effects. In Studies 2 (N=100), 3 (N=200), and 4 (N=222), chronically accessible information was a strong predictor of life satisfaction judgments, whereas item order had a relatively small effect. Study 5 (N=651) demonstrated that the results generalize to single item measures and judgments of shorter time periods. The results suggest that life satisfaction judgments are more heavily based on chronically accessible than temporarily accessible information.     

The Presentist’s Dilemma

This paper defends three theses: (i) that presentism is either trivial or untenable; (ii) that the debate between tensed and tenseless theories of time is not about the status of presentism; and (iii) that there is no temporal analogue of the modal thesis of actualism.     

Psychobiology of altered states of consciousness

The article reviews the current knowledge regarding altered states of consciousness (ASC) (a) occurring spontaneously, (b) evoked by physical and physiological stimulation, (c) induced by psychological means, and (d) caused by diseases. The emphasis is laid on psychological and neurobiological approaches. The phenomenological analysis of the multiple ASC resulted in 4 dimensions by which they can be characterized: activation, awareness span, self-awareness, and sensory dynamics. The neurophysiological approach revealed that the different states of consciousness are mainly brought about by a compromised brain structure, transient changes in brain dynamics (disconnectivity), and neurochemical and metabolic processes. Besides these severe alterations, environmental stimuli, mental practices, and techniques of self-control can also temporarily alter brain functioning and conscious experience.     

Memory for word location during reading: Eye movements to previously read words are spatially selective but not precise

In two experiments, readers' use of spatial memory was examined by asking them to determine whether an individually shown probe word had appeared in a previously read sentence (Experiment 1) or had occupied a right or left sentence location (Experiment 2). Under these conditions, eye movements during the classification task were generally directed toward the right, irrespective of the location of the relevant target in the previously read sentence. In two additional experiments, readers' knowledge of prior sentence content was examined either without (Experiment 3) or with (Experiment 4) an explicit instruction to move the eyes to a target word in that sentence. Although regressions into the prior sentence were generally directed toward the target, they rarely reached it. In the absence of accurate spatial memories, readers reached previously read target words in two distinct steps--one that moved the eyes in the general vicinity of the target, and one that homed in on it.     

Defocused attention in depressed mood: evidence from source monitoring

The authors suggest that depressed mood is associated with a defocused mode of attention, allowing irrelevant information to be noticed and processed more than in nondepressed states. Working on a source monitoring task, subclinically depressed college students selected with the Beck Depression Inventory (A. T. Beck, 1967; D. Kammer, 1983) had better memory for irrelevant stimulus aspects than nondepressed control students. However, depressed students' performance on the relevant stimulus aspects was unimpaired. These results are in conflict with a capacity reduction view of depressed mood and support the hypothesized altered, defocused mode, in which attentional resources are more evenly allocated across various aspects of the materials. The results are discussed within the framework of adaptive functions of emotional states.     

Interaction between reflexive fighting and cooperative escape

Subjects separated by a Plexiglas partition were trained to follow a cooperative escape procedure which produced behavior like the escape responding of individual subjects. Removal of the partition produced fighting and less efficient escape. Efficient escape behavior was restored and fighting disappeared when the partition was replaced. Neither increased space nor a moving toy affected escape behavior. The results indicate that switching animals from an isolated to a social situation produced a change in the effect of shock upon escape which was related to shock-induced fighting.     

A forty-three day avoidance session

A single Sprague-Dawley rat was subjected to an extended discriminated avoidance session in effect continuously for over 1000 hr (43 days). The longest possible shock-free interval that the subject could obtain without responding was 5 min. Since the subject did not sleep through shock, all resting or sleeping was interrupted at least once every 5 min by either a response or a shock. Neither the experimental (avoidance) animal nor a second animal which received all shocks not avoided by the first, gave any appearance of ill effects from the protracted session.
