This paper explores a judgmental heuristic in which a person evaluates the frequency of classes or the probability of events by availability, i.e., by the ease with which relevant instances come to mind. In general, availability is correlated with ecological frequency, but it is also affected by other factors. Consequently, the reliance on the availability heuristic leads to systematic biases. Such biases are demonstrated in...

Two forms of thinking about the future are distinguished: expectations versus fantasies. Positive expectations (judging a desired future as likely) predicted high effort and successful performance, but the reverse was true for positive fantasies (experiencing one's thoughts and mental images about a desired future positively). Participants were graduates looking for a job (Study 1), students with a crush on a peer of the opposite sex...

Existing models of intertemporal choice normally assume that people are impatient, preferring valuable outcomes sooner rather than later, and that preferences satisfy the formal condition of independence, or separability, which states that the value of a sequence of outcomes equals the sum of the values of its component parts. The authors present empirical results that show both of these assumptions to be false when choices...

To what extent are three criteria of daydreaming–as thought that is fanciful, stimulus-independent, or undirected–equivalent? How are these properties of thought flow distributed during everyday activity? Students (N = 29) carrying a beeper described properties of their consciousness on a total of 1425 occasions by means of a Thought-Sampling Questionnaire, anxiety and depression measures, and activity report forms. Intrasubject analyses of thought variables identified eight...

A survey was conducted to assess people's time orientation or where they spend most of their thinking time: past, present or future. 100 women were also asked about their expectations for the quality of life in 20 co 30 yr. and about the odds of a large-scale nuclear war within 30 yr. Respondents thought almost twice as much about the present and future as the...

The case of a 36-year-old man who suffers dense retrograde and anterograde amnesia as a result of closed-head injury that caused extensive damage to his left frontal-parietal and right parieto-occipital lobes is described. Patient K.C. has normal intelligence and relatively well-preserved perceptual, linguistic, short-term memory, and reasoning abilities. He possesses some fragmentary general knowledge about his autobiographical past, but he does not remember a single...

vDescribes laboratory and clinical attempts to relate different memory systems (procedural, semantic, and episodic) to corresponding varieties of consciousness (anoetic, noetic, and autonoetic). The case of a young adult male amnesic patient is described. The S suffered a closed head injury that left him without autonoetic consciousness. This deficit is manifested in his amnesia for personal events and his impaired awareness of subjective time. Two...

Adult humans are capable of remembering prior events by mentally traveling back in time to reexperience those events. In this review, the authors discuss this and other related capabilities. considering evidence from such diverse sources as brain imaging, neuropsychological experiments, clinical observations, and developmental psychology. The evidence supports a preliminary theory of episodic remembering, which holds that the prefrontal cortex plays a critical, supervisory role...

An experiment is reported that attempts to distinguish between anxious and depressive future thinking in terms of anticipation of future positive and future negative experiences. Anxious, mixed (anxious-depressed), and control participants were given an adapted verbal fluency paradigm to examine the ease with which they could think of future positive and negative personal experiences. Anxious participants differed from controls only in anticipating more future negative...
