Forced serial processing of words and letter strings: A reexamination

Words and nonword strings, three and seven letters long, were displayed serially (i.e., one letter at a time) or simultaneously, with or without a backward mask following display of each letter or string. Recognition of words, and of individual letters within words, was markedly impaired in the masked serial condition relative to the unmasked serial, unmasked simultaneous, and masked simultaneous conditions. Analogous differences were smaller or nonexistent for seven-letter nonwords; however, three-letter nonwords produced relatively “wordlike” data. Implications for the issue of spatially serial vs. parallel processing in word recognition are discussed.     

Infantile stimulation and its effects on frustration- and fear-motivated behavior in rats

Infant rats that were either removed from the nest each day (handled) or left undisturbed (nonhandled) were, in adulthood, given 72 food-reinforced runway acquisition trials followed by 24 trials of extinction training with or without shock. Handled and nonhandled control animals were given runway training without food reinforcement. Reinforced rats ran faster than nonreinforced rats, and handled rats ran faster than nonhandled rats during the initial trials of runway acquisition irrespective of the reinforcement condition. Nonhadled rats stopped running sooner than handled rats when shock was introduced in the goalbox, but differences between handled and nonhandled rats given extinction training without shock were small. Results of a second experiment showed no differences between handled and non-handled rats in the magnitude of the depression effect after an incentive shift. It was concluded that infantile handling had little effect on frustration-motivated behavior, but did affect fear-motivated behavior.     

The effects of forced serial processing on identification of words and random letter strings

Skilled readers identified words and random letter strings displayed one letter at a time on the screen of a computer-controlled oscilloscope. Letters were either displayed in a single position, or painted left-to-right in adjacent positions. Adjacent displays were either unmasked, masked by a letter-like pattern following each letter (backward masking) or masked by a pattern preceding each letter (forward masking). Unmasked words were identified with a high degree of accuracy, and accuracy was independent of the exposure duration of the letters over the range 50–200 msec. Masked adjacent word displays and one-position word displays were identified much less accurately, and accuracy was highly dependent on letter exposure duration. In contrast to these results, identification of random strings, or of letters within random strings, was almost unaffected by the presence of the mask and was dependent on letter exposure duration under all display conditions. The results are interpreted as evidence that (a) masking forces subjects to process serial displays one letter at a time, and (b) words, or large segments of words, are habitually processed in parallel, while random strings are processed as a series of individual letters or small chunks.     

The Marriage Contract

This article is intended to serve as an introduction to the concept of the marriage contract, which has proved to be a useful clinical tool for clarification and treatment of troubled marriages. Transactional as well as intrapsychic factors are important aspects of marital dynamics. The contract concept employs both these behavioral parameters and facilitates therapeutic intervention at both levels.     

Children's interpretation of adult nonreaction: A trial-by-trial self-report assessment and evidence for contrast effects in an observational context

The study investigated children's interpretation of blank reaction (nonreaction) from one adult to another as a function of its pairing with positive or negative overt feedback. Each child watched through a one-way mirror as an evaluating adult provided feedback to a second adult who was performing on a two-choice discrimination task. After six initial blank reaction trials, children observed one of four types of feedback combinations over 60 experimental trials: (a) right feedback on some trials and blank reactions on others, (b) wrong feedback on some trials and blank reactions on others, (c) right, wrong, and nonreaction on different trials, or (d) nonreaction on all trials. There was little evidence that children consistently interpreted blank reaction as meaning right independent of feedback combination. In contrast, in the Right-Blank and Wrong-Blank feedback combinations, children interpreted blank as meaning the opposite of the overt feedback it was paired with on over two-thirds of the trials, with no sex differences or test anxiety effects.     

Depth of Field: Using photographs and narratives to explore and reflect on ageing

The learning landscape of the higher education environment is changing, with an increased focus over the past decade on how educators might begin to cultivate reflective skills in health professions students. In addition, changing professional requirements demand that health professionals are adequately prepared to practise in today’s complex healthcare systems, including responding to changing demographics of population ageing. In this educational case study, we will share how we (a group of education, medical and nursing academics) developed ‘Depth of Field: Exploring Ageing’ a digital, consumer-driven, interprofessional reflective learning resource that uses photographs, narrative and small-group work to strengthen reflective capacity in current and/or future health professionals.     

Subjective trajectories for life satisfaction: A self-discrepancy perspective

Although the belief that life gets better and better over time is widespread, individuals who perceive their lives to be improving over time report less positive functioning. Here we report an experimental study based on self-discrepancy theory (Higgins in Psychol Rev 94:319–340, 1987) in which the type of future self-guide (ideal, ought, undesired, unspecified) was manipulated across young adult participants. Perceived self-discrepancy and subjective life satisfaction trajectories (derived from ratings of past, current, and anticipated future life satisfaction) were impacted as expected. Subjective trajectories (current-to-future) were associated with greater perceived discrepancies in the undesired future condition only. Emotional distress was associated with greater perceived discrepancy from a positive future (ideal, ought, unspecified) and more steeply inclining subjective trajectories (current-to-future), along with less perceived discrepancy from an undesired future and less steeply declining subjective trajectories (current to undesired future). Thus, temporal self-discrepancy may shape temporal life satisfaction evaluations and associated emotional reactions.
