Stimulus control over sex-typed play in cross-gender identified boys.

Discriminative stimulus control over masculine and feminine sex-typed play behaviors was investigated in five boys, aged 5–8 yr, with “childhood crossgender identification.” Reliable observational measures of play were obtained with two sets of toys: (a) “dress-up toys” (girls' apparel vs boys' apparel), and (b) “affect toys” (maternal-nurturance play vs masculine-aggression play). With an ABA reversal intrasubject design, certain stimulus conditions (e.g., presence of father, mother, male, or female stranger) were found to be discriminative for reliable changes in sex-typed play. Sex-typed play was found to vary as a function of the social stimulus situation and as a function of the type of play response required. All children played predominantly feminine while alone in the playroom. While no single environmental stimulus was consistently discriminative for masculine play across children, at least one stimulus condition was found for each subject under which he played predominantly masculine.     

Rough‐and‐tumble play in human children

Rough and tumble (R&T) play is a unique set of behaviors that can be reliably distinguished from aggression and other childhood activities. Although it may be the most fundamental form of play, it has received comparatively little experimental attention in the human species. Forty children, ages three to six, were allowed to play in pairs (10 male pairs, 10 female pairs) during a 30 minute videotaped session with no toys available while music played in the background during every other five‐minute time period. The incidence frequency of children's play and related behavioral activities were scored using 20 behavioral categories. The major findings show only modest gender differences in the frequency of play behaviors in such controlled social encounters; the main difference is that boys engaged in slightly more physical play solicitations than girls. Music facilitated General Motor Activities (e.g., Running and Walking behaviors), but not specific R&T play actions (e.g., Wrestling, Ventral and Dorsal contacts). Finally, most play behaviors as well as general activities declined systematically over the course of each recording session. This experiment highlights how human social play can be systematically studied in a controlled laboratory setting. Aggr. Behav. 29:539–551, 2003. © 2003 Wiley‐Liss, Inc.     

Effects of neutral toys on sex-typed play in children with gender identity disorder

This study assessed the relative influences of approach and avoidance behaviors toward same-sex and cross-sex toys in the play of children with gender identity disorder and in normal boys, normal girls, and psychiatric controls. Three forced-choice situations with toys and three forced-choice situations with dress-up apparel were presented that paired same-sex and cross-sex stimuli, same-sex and neutral stimuli, and cross-sex and neutral stimuli. In the same-sex/cross-sex situation, the gender-disordered group played a significantly shorter time with the same-sex stimuli and a significantly longer time with the cross-sex stimuli than the normal boys and the psychiatric controls, whereas the play patterns of the normal girls fell in between that of the gender-disordered group and the other two control groups. Within-groups analyses showed that the normal boys and the psychiatric controls preferred the same-sex toys, whereas the gender-disordered group and the normal girls showed no preference. When the neutral toys were the alternative, avoidance of cross-sex toys appeared to be stronger than the attraction to same-sex toys in the normal boys and in the psychiatric controls. The relative influence of approach-avoidance tendencies was more equivocal in the gender-disordered group, though they appeared to have a weaker attraction to same-sex toys and less avoidance of cross-sex toys in comparison with the normal boys and the psychiatric controls. The approach-avoidance patterns of the normal girls fell in between that of the gender-disordered group and the other two control groups.     

Patterns of toy play: An analysis of sex differences

Kindergarten children were videotaped playing with female- and male-traditional toys as well as nonsex-typed toys. Coders calculated time spent by each child in behavioral categories (positive and negative comments, aggression, nurturance, movement, noise, and gadgetry) and rated children on scales (talkativeness, activity, familiarity, enjoyment, proximity, appropriateness, and gentleness). Sex differences were revealed on most dimensions. Boys were rated as familiar with, enjoying, and playing appropriately with two toys (male-traditional and nonsex-typed) and girls on the female-traditional toy. Girls paid more attention to details of the toys, while there were few differences on aggression and movement. Data suggest that children develop varying patterns of play with the same toy—based on their earlier experiences with play materials. Agents promoting these differences (parents, teachers, and peers) are discussed, as are implications of the findings for children's development of skills and cognitive abilities.Portions of this report were presented at the annual meeting of the American Psychological Association, Toronto, August 1978. The author wishes to thank the San Bernardino Unified School District for help in conducting the research, and Lorraine Gorski and Dan Kelso for their work as coders.     

Side effects of extinction procedures in a remedial preschool

Several studies have shown that behavior modification procedures aimed at a single behavior may have effects on other, nonmanipulated behaviors. A young retarded boy engaged in excessive conversation with his preschool teacher. The teacher then began to ignore his initiated conversation during free-play periods, and it decreased. In addition, (1) social behavior relative to children increased, and (2) use of girls' toys decreased during free play. Also, (3) appropriate behavior at group academics declined, while (4) disruptions rose. In a second study, the teacher alternated conditions of praise and ignoring for talking with children. Talking with children varied accordingly. In addition, use of girls' toys and group academics disruptions rose during the ignoring condition. Appropriate behaviors dropped. Lastly, a timeout procedure was used to eliminate the undesirable side effects of disruptions and of use of girls' toys. Apparently, a response class may have member behaviors that covary directly and/or inversely. Some covariations may be socially desirable, others undesirable. The appearance of undesirable "side effects" can be controlled using behavior modification techniques.     

Some Parameters of Correspondence Training and Generalized Verbal Control

The effects of correspondence training on subsequent verbal control over play behavior with non- referred toys was investigated. Correspondence training resulted in subsequent verbal control for three of four children. It was also found that the group data, as typically presented in similar research, did not consistently reflect individual trends. Experiment II assessed generalization of verbal control across non-toy play behaviors. No generalization occurred. In both Experiments I and 11, maintenance of behavior change following correspondence training occurred only when no competing response was reinforced. Experiment III found that correspondence could be trained in the one child who failed to respond appropriately during Experiment I, by teaching her to recite a "correspondence rule."     

Increasing pretend toy play of toddlers with disabilities in an inclusive setting

We evaluated a program for increasing pretend toy play of 2-year-old children with disabilities in an inclusive classroom. Classroom personnel implemented the program, which involved choices of classroom centers containing toys that tend to occasion pretend play in toddlers without disabilities, along with prompting and praise. Increases occurred in independent pretend-play rates among all 5 participating toddlers. Results are discussed regarding the importance of promoting toy play of very young children with disabilities that is similar to the type of play of their nondisabled peers, and the need to identify critical program components that are applicable in inclusive settings.

The Impact of Parenting Experience on Gender Stereotyped Toy Play of Children

The purpose of this study was to examine gender role socialization as a function of parenting experience in an actual toy play situation and as a function of adults' perceptions of typically gender-stereotyped children's toys. Each of 48 children (24 boys and 24 girls) played with 3 adults: either his or her own mother or father, a matched mother or father of another child, and a matched man or woman who was not a parent. The amount of time children and adults played with gender-specific toys, adults' categorization of toys into gender categories, and adults' desirability ratings of gender-specific toys were examined. The gender-sorting task revealed that adults did not agree with traditional expert categorizations of some of the toys, which suggests a shift in the perceived function of some traditionally stereotyped toys. Regardless of how parents sorted toys into categories, when playing with boys, most time was spent with masculine toys. With girls, however, there was greater flexibility in the categories of toys with which they played. Parenting experience influenced the perceived desirability of toys; parents found toys more desirable than nonparents but these differences did not affect the actual play session with children. These results suggest a change in perceptions of traditionally stereotyped toys and differences as a function of gender in what is appropriate gender-typing behavior.     

Gender-Typing of Children’s Toys: Causes,Consequences, and Correlates

Gender differences in children’s toy interests and play behaviors are large and may lead to gender differentiation of physical, cognitive, and social development among children. In this Special Issue, we gather together cutting-edge research on the factors that affect gender differences in children’s toy interests, how subtle gender-related messages affect children’s performance and behaviors, and how adults create these gender-related messages and affect children’s interests. We illustrate themes found in the current literature, but also comment on issues that need to be addressed by future research. We also identify points of intervention in which stereotypes about toys and gender differentiated play behaviors and toy interests can be reduced in an effort to promote greater diversity of children’s play.     

Promoting imitative play through generalized observational learning in autisticlike children

Three autisticlike boys with deficits in imitative and appropriate play behaviors were taught to play with an unfamiliar toy by observing a peer model demonstrate appropriate play with the toy. Generalization was assessed across toys and models, and temporal maintenance was assessed at 1 and 3 weeks following generalization. Following training each child demonstrated increases in imitative play concomitant with decreases in the frequency of nonmanipulated selfstimulatory behavior. Results are discussed in terms of their implications for the amelioration of social isolation and self-stimulatory behavior.The authors wish to acknowledge the help and cooperation of the Henry Wiseman Kendall Center and the Highpoint Preschool Enrichment Program.     

儿童2-4岁的行为抑制性对其陌生同伴交往的预测

该研究用纵向追踪的实验室观察研究了儿童2岁、4岁时的行为抑制性,及其4岁时与陌生同伴交往特征的关系。结果发现：儿童2岁时的抑制性能预测其在4岁时的社交发起行为缺乏,但不能预测各种游戏活动类型。儿童4岁时的行为抑制性与其单独一被动活动、平行活动及社会互动活动呈显著负相关;与交往中的抑制行为呈显著正相关;儿童4岁时的抑制性分数能预测儿童交往的主动性的缺乏。稳定极端抑制儿童和稳定极端非抑制儿童在抑制行为、平行游戏、社会互动游戏、社交发起和玩新奇玩具方面存在显著差异。     

Sex-typed play of toddlers in a day care center

By the age of 3, boys prefer gross motor and vehicle play and girls prefer doll and housekeeping play. The present study was an attempt to define the age at which these sex differences first appear by observing the play behavior of one- and two-year-olds in a day care center. We observed use of stereotyped toys in children 15 to 35 months old during free play. Boys played more with the masculine toys than with either of the other types, whereas girls showed almost equal use of all three types. Choice of sex-typed toys was more prevalent among older boys, while older girls showed less play with feminine toys than younger girls.     

“Pretend you didn't know”: Preschoolers' talk about mental states in pretend play

Fifty preschoolers (mean age = 47 months; SD = 5 months) were recruited from local inner-city nurseries to take part in a study of early friendships and the development of social understanding. Friendship pairs (10 boy-boy pairs; 10 girl-girl pairs and 5 boy-girl pairs) were filmed playing together for 20 minutes in a quiet room supplied with toys and dressing-up materials. The videos were then transcribed and coded for mental-state talk and pretend play. The children were also given a battery of tests tapping theory-of-mind skills and verbal ability. The results indicated a strong association between children's engagement in pretend play, and the frequency and nature of mental-state talk. This association is discussed in relation to (1) effects of context, (2) individual differences in children's understanding of mind and verbal ability, and (3) the social nature of pretend play.     

Play behaviors of handicapped preschool children in the presence and absence of nonhandicapped peers

Sixteen minimally handicapped children and 18 nonhandicapped children were observed playing as separate classes and as a combined group on their preschool playground. Play behaviors directed toward self, toys, teachers, and peers were recorded using a time sampling procedure. Repeated measures analyses revealed that: (1) handicapped children engaged in less peer-directed and more teacher-directed behaviors than the similar chronological age but developmentally more advanced normal children; (2) a comparison between a subsample of normal and handicapped children who were approximately equivalent on developmental age suggested that the normal children only vocalized more often; (3) when integrated with the normal children, handicapped children engaged in more peer-directed and less teacher-directed behaviors than when playing in the non-integrated situation; (4) during the combined group play situation, normal children directed more behaviors to their own classmates while handicapped children directed approximately equal amounts of behavior to their own classmates and to their normal peers. These results suggest that the normal children were not negatively affected and the handicapped children were positively affected by the integrated play situation.     

An evaluation of stimulant medication on the reinforcing effects of play

Although a vast literature has indicated that stimulant medications are effective for reducing inappropriate behavior in children with attention deficit hyperactivity disorder (ADHD), the effects of stimulant medication on ancillary behaviors (e.g., play) have yet to be investigated with the same rigor. We used a reinforcer assessment procedure to evaluate the effects of medication on the play and social behavior of 5 preschool children who had been diagnosed with ADHD. Conditions included (a) social reinforcement (i.e., playing with friends), (b) alone play, and (c) quiet time (i.e., resting). Results indicated that 1 of the 5 participants selected fewer social reinforcers and more nonsocial reinforcers (alone play or quiet time) while on medication. The findings indicate that the reinforcer assessment procedure may be a viable way to evaluate medication effects on an ongoing basis and to inform treatment decisions.     

Teacher and peer reactions to boys' and girls' play styles

Seventy children (35 boys and 35 girls) aged 24 to 30 months were observed in play groups consisting of 12–15 2- and 3-year-old children and two teachers. The social interaction was coded using an observation schedule which allowed for coding the children's behaviors and reactions to that behavior by others in the environment. The behavior scores were factor analyzed, using the complete sample of 180 children with six factors (play styles) resulting. Children who were high and low on each factor were examined to see if play style influenced the type of social reaction received. Children who preferred to work at tasks quietly received positive teacher feedback, but there was no change in peer interaction; children who engaged in active motor play received positive peer feedback, but negative teacher reactions. Children who were passive received less peer reaction and played alone significantly more than other children. Sex differences in reactions did not appear except when the child was engaged in male- and female-typical behaviors when examining scores on one factor only. When combinations of factors are examined (e.g., activity level and task performance), then different patterns of responses start to appear for boys and girls. The implications for differing patterns of social reactions to different play styles are discussed.Data analyses were supported by BRSG Grant RR07980 awarded by the Biomedical Research Support Grant Program, Division of Research Resources, National Institutes of Health. The final write-up was completed on a postdoctoral fellowship (Grant No. 1 T32 MH 16955-01) through the Oregon Social Learning Center.     

The relations between sex-typed play and preschoolers' social behavior

For decades toy choice has been a very popular measure of children's sex-role adoption. In the present study, the relations between choice of masculine, neutral, or feminine toys and other social behaviors (sex typed and non-sex typed) were examined. The social behaviors (socializing, requesting assistance, prosocial behaviors, aggressive/defensive behaviors) and toy choices of 33 preschool children were observed in their classrooms. Only two behaviors were found to be sex typed (socializing with peers and spontaneous prosocial behavior), and both of these behaviors were related to toy choice. Toy choice was also related to helping. Among boys, masculine toy choice was associated with requesting assistance from teachers. When toy choice was classified as masculine, androgynous, and feminine, only sociability toward peers was related to toy choice. The results are discussed in terms of their implications for the continued use of toy choice as a measure of sex-role adoption.The authors wish to express their gratitude to Rene Dodez for her assistance in data analysis and to the children and teachers at the Child Study Laboratory.

Promoting social initiation in children with autism using video modeling

A large number of studies have shown that children and youths with autism can improve their social skills when provided with appropriate and well planned treatment strategies. Here, a video modeling procedure was implemented with seven developmentally delayed children, using a multiple‐treatment design. Each child watched a videotape showing a model and the experimenter engaged in a simple social interactive play in an adapted play setting. Afterwards each child's behavior was assessed in this setting, while the experimenter's behavior remained the same as that shown in the videotape. The video modeling training enhanced the social initiation skills of four children. It also facilitated appropriate play engagement, which generalized across settings, peers, and toys. These changes maintained after a 1‐ and 2‐month follow‐up period. The intervention was evaluated as a time‐efficient teaching tool as well as a means of enhancing appropriate play skills.
