The effects of instructional variables on young children's organization and free recall

The relationship between verbal instruction and children's free recall was examined. Sixty first-grade children (mean age 84 months) were trained to categorize pictures of common objects. Half were given organizational instructions emphasizing categorization, and half were given instructions emphasizing the individual objects. Similarly, half were given detailed verbal instructions and encouraged to listen, and half were taught using a question type format that encouraged participation. Immediately and after a 2- to 3-week delay, children who were shown an organizational strategy categorized the materials during study and attained higher recall scores than children who were shown a specific strategy. After the 2- to 3-week delay, children in the explanation groups out-performed children in the question-asking groups. The child's competence as measured by intelligence and performance in school did not contribute to amount recalled when subjects were given instructions emphasizing the general strategy. However, children of high competence benefited more from specific training by recalling more items than did children of low competence. These findings point to the importance of instructional variables in studying changes in children's processing capabilities.     

Case Study: A Quantitative Report of Early Attention,Fear, Disgust,and Avoidance in Specific Phobia for Buttons

Specific phobia is characterized by elevated early attention to the phobic object, negative emotion, and avoidance. Typically, phobic objects are biologically relevant, such as potentially threatening snakes or spiders, or potentially contaminating needles or rodents. It is unclear whether the same early attention, emotion, and avoidance responses can be observed in phobia for uncommon, nonbiologically relevant objects, such as buttons (koumpounophobia). In an experimental case study, we measured early attention (detection rates to briefly presented images before a backward mask), emotion, and avoidance to clothing buttons in a button-phobic participant. We compared these responses to nonphobic objects (zippers), and to well-matched control participants. We observed elevated early attention, fear, and disgust to buttons, which did not generalize to nonphobic emotional stimuli. In addition, we observed elevated avoidance of buttons, which did generalize to normatively fearful and disgusting pictures. If replicated, our results indicate that nonbiologically prepared phobic objects elicit similar elevated early attention, emotion, and avoidance as biologically prepared phobic objects. The finding that avoidance was the only response that generalized to nonphobic objects may have treatment implications—namely, that therapeutic attempts to reduce avoidance might consider including a variety of objects, not just the phobic object.     

Recognition and recall by children and adults as a function of variations in memory encoding instructions

In four experiments Ss were instructed to learn a set of 40 words by producing implicit associative responses to each item (association instructions), by repeating items over and over (repetition instruction), or by using their own devices (neutral instructions). Experiment I showed that recognition memory (RM) accuracy was greatest under association instructions for adults and children and least under repetition instructions for children. The implications of these results for a frequency theory analysis for RM were discussed. Experiments II, III, and IV examined free recall (FR) as a function of encoding instructions at short (1 min) and long (either 90 min or 24 h) retention intervals. FR was worst under repetition instructions, with little overall difference between the association and neutral conditions. However, in Experiments III and IV, using school children, the neutral condition exceeded the others in FR after 90 min but not after 1 min.     

Effects of reinforcement and guidance procedures on instruction-following behavior of severely retarded children

Positive reinforcement, physical guidance, and fading procedures were used to teach two severely retarded children motor responses to a variety of verbal instructions. Subjects' responses to one set of instructions provided the focus for the training procedures. Their responses to a second set of instructions were used to assess the generalized effects of training. The frequency of responses to both sets of instructions was evaluated during Baseline 1, Training 1, Baseline 2, and Training 2 periods. During the training periods, this evaluation was made after the daily training sessions when no training procedures were in effect. Results indicated that the subjects showed pronounced increases in instruction-following behaviors (both trained and untrained) during training periods with decreases in such behavior occurring during the Baseline 2 period. The general findings demonstrate the applicability of the training procedures for producing and maintaining instruction-following behaviors in severely retarded children and for facilitating appropriate responding to instructions not directly involved in training.     

Emergent completion of multistep instructions via joint control

Teaching procedures that facilitate the emergence of novel responses allow for increased efficiency, which is critical when providing early-intervention services to children with autism spectrum disorder (ASD). Three 5- and 6-year-old children diagnosed with ASD participated. In Experiment 1, we demonstrated functional control over the effects of teaching echoic rehearsals on the emergence of completing novel two-step instructions via joint control and obtained generalization and maintenance of the effects in an applied, nontraining context. In Experiment 2, we conducted an experimental analysis of joint control by disrupting rehearsal of the instruction and tacts of the objects in the instruction, which served as the sources of joint control. Our results support the efficacy of the procedures for establishing first-trial performance with novel instructions and indicate that joint control is responsible for the emergent performance produced by our teaching procedures.     

Event frequency and children's suggestibility: a study of cued recall responses

Research examining the effect of repeated experience on children's suggestibility for particular kinds of information has produced differing results. In one study, responses to recognition questions revealed heightened suggestibility for variable details in children who repeatedly experienced an event compared to children who experienced an event once. In other studies, no such effect was found with cued recall. In this study, 4–5‐year old children engaged in one or four play sessions. Children were later given a biasing interview wherein half of the details were incorrectly represented. Children were then given a final memory test using free and cued recall prompts that was preceded by one of three instruction types: no special instructions, moderate instructions, or opposition instructions. Children in the repeated‐event condition were more suggestible than those in the single‐event condition, regardless of instructions. No significant differences in suggestibility were found across instructions conditions. Copyright © 2004 John Wiley & Sons, Ltd.     

On the young child's use of lexis and syntax in understanding locative instructions

The ability of two and three year old children to comprehend in, on and under was tested in five contexts. In the first context, where responses did not depend on the child manipulating the experimental objects, responses were invariably correct except for some difficulty with under in the youngest subjects. In the other four contexts, which did involve manipulation of the objects by the child, responses varied as a function of the noun phrases used to refer to the experimental objects which themselves remained the same across different contexts. The result suggest that the young child's comprehension of instructions involves an interaction between aspects of the instruction's lexis and syntax and the child's construal of context.     

The effects of instructional set on physiological response to stressful imagery

Centrally mediated or cognitive variables have received considerable attention in clinical research. With the establishment of the effectiveness of such specific treatment techniques as systematic desensitization (Paul. 1969a. 1969b). a question arises as to the influence of cognitions on process and outcome variables in such learning based treatments (Lang. 1971). Research investigating the influence of demand characteristics and subject expectancies has demonstrated such centrally mediated variables can significantly influence overt, behavioral and self-report measures of fear, stress, or anxiety (cf. Borkovec. 1972: Marcia. Rubin and Efran. 1969; McGlynn. Maelia and Nawas. 1969: McGlynn. Reynolds and Linder. 1971: Oliveau. Agras. Leitenberg and Wright. 1969; Rappaport. 1972: Rosen. 1974).However. Borkovec (1972) and Rappaport (1972) failed to obtain expectancy effects on physiological measures of anxiety. Neither investigation provided for an independent assessment of subjects' actual expectancies, or belief in the instructions, as recommended by Davison and Wilson (1973). Borkovec administered clinical procedures over four sessions and varied the information communicated about the ‘purpose’ of the treatments (physiological versus therapeutic instructions). Differential rationales for differential expectancies of physiological reactivity were not provided. After each session, subjects reviewed the same false physiological records depicting reductions in fear responses. Although these changes were explained either physiologically or therapeutically. the fact that such reductions were emphasized should have attenuated differences between groups. Rappaport (1972) exposed subjects to a fearful stimulus and varied the suggestion and rationale for the pseudotreatment: no expectancy (stress research): therapeutic expectancy (fear reduction); and negative expectancy (fear increase). The lack of an independent assessment of the expectancy manipulation, as well as the exclusion of a specific therapeutic procedure, make it impossible to interpret the results in relation to expectancy effects on physiological fear responses during the administration of therapeutic procedures. There is other evidence, however, that suggestion and instructional set can significantly influence somatic and autonomic response systems (Barber. 1961. 1965; Sternbach. 1964. 1965).The primary purpose of this study was to evaluate the effects of instructional set on physiological responses to stressful imagery. This was an early step in a research program investigating the effects of instructional and informational variables on physiological responses of clinical interest. One half of the subjects received abbreviated live relaxation training (R) as described m a manual by Bernstein and Borkovec (1972) and based upon the original work of Jacobson (1938). The other half received an inert placebo pill and undertook a target detection task (P). The latter procedure was similar to that used by Paul (1966). Although both procedures had previously been shown to have relaxing effects, the P task was included as an additional control for any potential effects specific to the tension-release procedure of R. In order to evaluate the effects of instructional set, one half of each of the above two groups received instructions designed to lead to an expectancy of response inhibition to stressful imagery by the respective procedure (Decrease Stress Response. DSR). while the other half received instructions designed to lead to an expectancy of an increased response to stressful imagery by the respective procedure (Increase Stress Response. ISR). Each subject visualized three individually specified items that were the most frightening scenes imaginable prior to training and four times after training visualized the scene producing the largest response. Considerable effort was devoted to eliciting from each subject the most frightening items possible for her. and it was clear from subject comments that the items did elicit negative emotional responses.Since previous research (Barber. 1961. 1965; Sternbach. 1964. 1965) indicated that instructional set can influence physiological reactivity, it was hypothesized the DSR) subjects should exhibit a greater reduction in emotional response from pre- to posttraining than ISR subjects.     

Artistic Creativity and Rorschach Whole Responses

The present experiment investigated artistic creativity as it functions in the production of whole responses to Rorschach ink blots. The number, percentage, and quality of whole responses produced by a group of artists were compared to that of a group of nonartists under two instructional sets (regular instructions versus whole response set). Artists and nonartists did not differ significantly in whole response quality. Artists and nonartists gave significantly more whole responses under the whole response set, but artists produced a significantly greater number of whole responses, regardless of instructions. Artists gave a significantly greater proportion of whole responses only under regular instructions. These results give statistical verification to the discriminatory power of Rorschach whole responses in the identification of artistic creativity.     

The impact of anxiety on analogical reasoning

The effect of state anxiety on analogical reasoning was investigated by examining qualitative differences in mapping performance between anxious and non-anxious individuals reasoning about pictorial analogies. The working-memory restriction theory of anxiety, coupled with theories of analogy that link complexity of mapping with working-memory capacity, predicts that high anxiety will impair the ability to find correspondences based on relations between multiple objects relative to correspondences based on overlap of attributes between individual objects. Anxiety was induced in one condition by a stressful speeded subtraction task administered prior to the analogy task. Anxious participants produced fewer relational responses and more attribute responses than did non-anxious participants, both in the absence of explicit instructions to find relational mappings (Experiment 1) and after receiving such instructions (Experiment 2). The findings support the postulated links among anxiety, working memory, and the ability to perform complex analogical mapping.     

Learning,awareness, and instruction: Subjective contingency awareness does matter in the colour-word contingency learning paradigm

In three experiments, each of a set colour-unrelated distracting words was presented most often in a particular target print colour (e.g., “month” most often in red). In Experiment 1, half of the participants were told the word-colour contingencies in advance (instructed) and half were not (control). The instructed group showed a larger learning effect. This instruction effect was fully explained by increases in subjective awareness with instruction. In Experiment 2, contingency instructions were again given, but no contingencies were actually present. Although many participants claimed to be aware of these (non-existent) contingencies, they did not produce an instructed contingency effect. In Experiment 3, half of the participants were given contingency instructions that did not correspond to the correct contingencies. Participants with these false instructions learned the actual contingencies worse than controls. Collectively, our results suggest that conscious contingency knowledge might play a moderating role in the strength of implicit learning.     

Mental context reinstatement or drawing: Which better enhances children's recall of witnessed events and protects against suggestive questions?

The aim of this experiment was to examine the effectiveness of two techniques in enhancing children's recall of an event that they experienced approximately a week earlier. Younger (5–6 years) and older (8–9 years) children were interviewed about a magic show event in one of three conditions. Before recalling the event, some children were instructed to mentally reinstate the context of the event (MCR group), others were asked to draw the context of the event (DCR group), and others received no reinstatement instructions (NCR). Results showed that these instructions had no impact on children's free recall or responses to open‐ended prompts. However, reinstatement instructions impacted children's responses to suggestive questions: those in the DCR group gave more accurate responses than those in the NCR group. These findings provide preliminary support for the use of drawing as a potentially protective exercise that lessens the impact of biased questions with child witnesses.     

Developmental aspects of memory for spatial location

The purpose was to show whether or not the encoding of location met criteria defining an automatic process (L. Hasher & R. T. Zacks, 1979, Journal of Experimental Psychology: General, 108, 356-388; 1984, American Psychologist, 39, 1372-1388). Among other criteria, automatic processes are not expected to show developmental changes beyond an early age, to be unrelated to intelligence level, and to be unaffected by instructions. In the first experiment preschool through sixth-grade children were compared on a 40-picturebook task following incidental (remember the names of pictures) or intentional (remember location) instruction. Subjects viewed and named pictures in sets of four, arranged in quadrants in the opened book, and then attempted to recall names of the objects pictured and to relocate pictures on blank pages. In the second experiment, second and sixth graders, college students, elderly persons, and mentally retarded persons were compared on a 60-picturebook task following either incidental or semantic incidental instructions (give the function of objects pictured). Memory for location was invariant across age groups and intelligence level. The only exception was that 3 and 4 year olds were more accurate following intentional instructions. Otherwise there were no differences between intentional and incidental instructions. Semantic instructions resulted in slightly more accurate locations. The results were interpreted as supportive of the Hasher and Zacks' automaticity hypothesis.     

Future thinking improves prospective memory performance and plan enactment in older adults

Efficient intention formation might improve prospective memory by reducing the need for resource-demanding strategic processes during the delayed performance interval. The present study set out to test this assumption and provides the first empirical assessment of whether imagining a future action improves prospective memory performance equivalently at different stages of the adult lifespan. Thus, younger (n?=?40) and older (n?=?40) adults were asked to complete the Dresden Breakfast Task, which required them to prepare breakfast in accordance with a set of rules and time restrictions. All participants began by generating a plan for later enactment; however, after making this plan, half of the participants were required to imagine themselves completing the task in the future (future thinking condition), while the other half received standard instructions (control condition). As expected, overall younger adults outperformed older adults. Moreover, both older and younger adults benefited equally from future thinking instructions, as reflected in a higher proportion of prospective memory responses and more accurate plan execution. Thus, for both younger and older adults, imagining the specific visual–spatial context in which an intention will later be executed may serve as an easy-to-implement strategy that enhances prospective memory function in everyday life.     

The Effects of Subject-and Experimenter-Induced Defensive Response Sets on Picture-Frustration Test Reactions

Thirty male college students, half scoring high and half low on the MMPI K-scale, were administered a multiple-choice (M-C) modification of the Rosenzweig P-F Study under three instructional sets. Two of these sets were induced by E and compared with the third which represented S's normal test-taking set. The two induced sets included (1) a “should” set in which concern for the social consequences of behavior was accentuated, and (2) a “wish” set in which concern for social consequences was minimized, and freedom of self-expression was accentuated.

It was hypothesized that Ss making extremely high or low scores on the K-scale would likewise score differently on the M-C, P-F test. High K, defined by its authors as a measure of test defensiveness, and low K, as test-taking candidness, would be associated with P-F score patterns reflecting these test-taking attitudes: High K Ss showing Impunitive (M) dominant reaction patterns and low K showing Extrapunitive (E) or Intropunitive (I) dominant patterns. These hypothèses were confirmed except that intropunitive responses were extremely rare in the entire subject sample.

It was further hypothesized that the typical high K pattern would be induced in low K Ss under the “should” instructional set and the low K pattern would be elicited from high K Ss under “wish” instructions. This expectation was confirmed. It was suggested that the technique of manipulating responses via test taking instructions can generate correction factors useful in projective as well as structured personality tests.     

Classifying by dimensions and reading: a comparison of the auditory and visual modalities

Children have difficulty learning to read alphabetic writing systems, in part, because they have difficulty segmenting spoken language into phonemes. Young children also have difficulty attending to the individual dimensions of visual objects. Thus, children's early difficulty in reading may be one sign of a general inability to selectively attend to the parts of any perceptual wholes. To explore this notion, children in kindergarten through fourth grade (Experiments 1, 3, and 4) and adults (Experiment 2) classified triads of spoken syllables and triads of visual objects. Classifying speech by common parts was positively related to reading and spelling ability (Experiments 1 and 4), but usually not to classifying visual stimuli by common parts under free classification instructions (Experiments 1 through 3). However, classification was more consistent across the visual and auditory modalities when the children were told to classify based on a shared constituent (Experiment 4). Regardless of instructions, performance on the visual tasks did not usually relate to reading and spelling skill. The ability to attend selectively to phonemes seems to be a "special" skill--one which may require specific experiences with language, such as those involved in learning to read an alphabetic writing system.     

The impact of stimulus-specific practice and task instructions on response congruency effects between tasks

In task switching experiments participants have to respond to the same set of stimuli while task instructions vary (e.g., digit stimuli are assigned to left- or right-sided key presses by means of magnitude vs. parity classification). Response congruency effects denote worse performance for a stimulus, which is associated with different responses in the two tasks as compared to a stimulus, which is associated with the same response. Previous research suggests that such effects reflect direct links between stimuli and responses acquired in the course of experimental practice. In the current study we investigated the impact of stimulus-specific practice and task instruction by reversing the S–R mapping of one task (Experiment 1) or replacing one task with a new one (Experiment 2) in the second half of an experimental session. Consistent with the direct link account, S–R links practiced during the first half of the experiment largely determined congruency effects despite altered task instructions. Furthermore, the results suggest that previously practiced S–R links (a) can be relatively quickly overwritten by practicing a novel S–R mapping, and (b) are subject to passive decay when no longer in use.     

Effects of capacity demands on picture viewing

Effects of cognitive-resource demands on picture-viewing patterns were investigated. The eye fixations of 72 subjects were recorded as the subjects viewed pictures and concurrently performed one of three listening tasks. Half of the subjects were asked to remember certain objects from the pictures and half had no-memory instructions. Concurrent auditory monitoring increased interfixation distances and the frequency of fixations on regions of high informativeness, and decreased the area of the pictures explored and the memory for objects in the scenes. it is suggested that the demands on cognitive resources influenced subjects’ ability to encode and integrate fixated information and therefore prolonged the normal first phase of viewing, described by Buswell (1935).     

A response set analysis of developmental differences in children's moral judgments

The study tested the hypotheses that 1) children may not adopt a moral response set when faced with moral dilemmas and 2) their knowledge of what constitutes a moral constellation of behaviors may differ from that of adults and may lead to developmental differences. To test these hypotheses, the study examined children's responses to a multiple choice moral dilemmas questionnaire under neutral instructions, instructions to answer as a good child or as a bad child. Subjects in fourth and seventh grade were asked whether a story hero would transgress and were required to justify their answers. In addition, questions regarding affective reactions to transgressions, confessions, and due punishment were asked. Fourth grade children answering in the good child instructions condition tended to give significantly different responses than under neutral instructions, while seventh grade subjects did not tend to differentiate between these two instruction conditions. While adult theories of morality would predict a differentiation between good and bad child instructions, on some of the measures no differences were found between good and bad child instructions. The implications of these results for cognitive-developmental theory were discussed and a general framework for interpreting the data was offered.     

The role of relational similarity in young children’s use of a scale model

The role of relational similarity in 3-year-old children’s understanding of the relation between a scale model and the space it represents was investigated in two studies. Relational similarity was manipulated by arranging the objects within the two spaces in either the same or different configurations; thus, the internal relations among the objects were either identical or very different. The pattern of results across studies revealed that multiple factors interacted to determine the children’s appreciation of the higher-level model–room relation. When other information about the model–room relation was provided via explicit instructions (Experiment 1), relational similarity did not affect performance. However, relational similarity did have a significant effect on performance when only minimal information regarding the model–room relation was given (Experiment 2). These results established that the children were sensitive to the relations among the objects within each space, as well as to whether those relations were similar across spaces. Furthermore, the results indicated that successful performance was supported by appreciation of the higher-level model–room relation, not merely the detection of individual object correspondences.
