Increased activity during the teaching of spelling words resulted in hyperactive children having greater difficulty than the normal children in distinguishing relevant tasks from the extraneous stimulation. (Ed.)

This paper presents a simple random procedure for selecting subsets of stimulus pairs for presentation to subjects. The resulting set of ratings from the group of subjects allows the construction of a group space through the use of an existing computer program. (Author/JKS)

The ability of 5-month-old infants to process relational information was assessed by means of a habituation-dishabituation paradigm with cardiac deceleration as the response measure. (SB)

Compared was the trace and delay eyelid conditioning in 72 severely or profoundly retarded and 72 normal young adults. (CL)

This study provided data showing that with increase in age there is an increase in spontaneous alternation behavior in preschool children. Mental age rather than chronological age is indicated as a more meaningful predictor of a child's tendency to seek out and approach varying stimulation. (GO)

Examined the effects of an audiovisual distractor on the visual attention paid to TV by preschool children characterized as distractible. The effectiveness of an audiovisual distractor eliciting a head turn from the TV was diminished when TV viewing had been maintained for at least 15 seconds. (PCB)

Tested the model which posits that heart-rate deceleration and respiratory sinus arrhythmia are indices of infant attention. Infants studied cross-sectionally at 14, 20, and 26 weeks of age were presented with complex patterns on a TV screen which were accompanied by an "interrupting stumulus". (Author/BN)

An investigation was conducted to equate auditory and electrocutaneous stimuli. These equated stimuli were used in a second investigation examining neuromotor responses to stimuli of varying intensity. Results are provided. (Author/MT)

The postural-sway response of five learning disabled (LD) and five nondisabled children was evaluated using a force platform. From statistical analysis of the two groups, the LD children appeared to use visual input to compensate for postural problems and had significant difficulty controlling posture with eyes closed.

To investigate the effect on young children's coding of spatial information, an array of boxes was varied in number, size, and arrangement and was shown to 20 toddlers. Only the number of boxes defining the left and right sides of the array influenced performance; that is, multiple boxes were associated with the use of external objects as spatial…

The acquisition of productive intraverbal behavior involving the emission of thematically related responses was evaluated with three mentally retarded children (13-16 years old). Training was conducted using an errorless discrimination procedure (prompt delay) and a variation to transfer vocal responses from control of visual stimuli (tact…

Examines discrimination of geometric shapes by three-month-old infants who were presented with geometric stimuli moving laterally at two different velocities. Finds that subjects discriminate between geometric forms at velocities that, according to previous findings, might interfere with shape discrimination. Discusses the possible interactive…

The constant task condition in which only trials on the target task were presented during each session led to faster response acquisition by two of four autistic children (9-10 years old) than the varied task methods in which trials for three nontarget tasks were interspersed with trials for the target task.
