The purpose of the study was to Compare the efficacy of an averaging (congruity) formula vs. an additive formula for the evaluation of complex stimuli when negative adjectives were used to describe the attitude topic. A logarithm formula proposed by Mannis, Gleason, and Dawes was also used. (DB)

Effects of location of electroconvulsive treatment (either the right or left side of the patient's head) are discussed. (CD)

Differences were found in the ease with which newborn infants habituate to stimuli in different modalities and in the ease with which different responses habituate to the same stimulus. (MH)

Based on PhD thesis submitted to the University of Iowa.

Thirty-one infants ages 8 to 16 days were shown a ball, a ball picture, and a homogeneous stimulus card. Infants' reaching behavior was scored for each of the stimuli according to the following: (1) lateral extension of arm, (2) arcing movement of arm toward midline, and (3) flexion of arm toward the upper half of the body.

Results from one experiment indicated that the temporal pattern and spectral complexity of moderately intense auditory stimuli influenced cardiac responses in 24 alert newborns. A second study extended the temporal-pattern effect to other vowel stimuli in a no-delay discrimination paradigm. (Author/RH)

An adaptive up/down tracking procedure was used in combination with a visually reinforced head-turn response to examine infants' (6 to 18 months of age) auditory sensitivity for 500-, 2000-, and 8000-Hz tone bursts. Six-month-olds were significantly less sensitive to the 8000-Hz tone than to either lower frequency; older infants demonstrated…
