Two experiments explored some implications of the idea that the visual perception of contour is determined by the efferent readiness activated by the visual input. The 5"s wore prisms on a contact lens, and visual adaptation to the prismatically induced .curvature was measured. The following findings are reported: (a) There is more adaptation and aftereffect with saccadic eye movements than with smooth tracking eye movements; (&) after saccadic eye movements, interocular transfer of aftereffects is greater than 70%; (c) the same results are obtained whether the eye fixates one point or moves freely during measurement; (d) there is evidence for conditional cumulative effects over a series of days.

This study examined the performance of high-and low-susceptible Ss under hypnotic and waking conditions when exhortative, analgesic, and other instructions were separately controlled and not confounded. 50 female Ss, assigned to 1 of 3 experimental or 2 control groups, performed 2 maximum effort tasks (Hand Dynamometer and Weight Endurance) and 1 skilled task (Tremor) in a Base Rate and a Special Instruction session. Except for 1 control group that always performed awake, all Ss performed both hypnotized and awake in both sessions. Special instructions facilitated performance in the hypnotic but not the waking state, and exhortative were more effective than analgesic instructions.

Earlier results which mdicated enhancement of performance in hypnosis over wakmg conditions have been brought mto senous question by a number of expenments, so that the issue is agam open For example, London and Fuhrer (1961), Slotnick and London (m press), and Levitt and Brady (1964) failed to find any superiority for performance in the hypnotic state over wakmg performance Slotmck and London found, however, that there was an mteraction between the hypnotic state and motivatmg mstructions, so that even though under hypnosis alone Ss performed less well than m the waking state, when exhortation was added to hypnosis, the hypnotic Ss gamed more than Ss for whom exhortation was added to wakmg mstructions The experiment reported here explores further this mteraction effect between instructions of a particular kmd and hypnosis, as they mcrease muscular performance SubjectsThe Ss were 12 female students who had participated m other experiments m the laboratory so that their general level of hypnotic performance was known They were m the upper 20 per cent of hypnotic susceptibihty as measured by the Stanford Hypnotic Susceptibihty Scale (SHSS), Form A (Weitzenhoffer & Hilgard, 1959), all scormg 8 or more on the 12-pomt scale Two of us (R S S and R M L ) served as Es, with Ss assigned at random The same E was responsible for both sessions with an S 1 A report from the program of research on hypnosis earned out m the Laboratory of Human Development with the aid of a grant to Emest R Hilgard from the Nabonal Institute of Mental Health (Grant M-3859) The assistance of other members of the research team m makmg available the pool of Ss from which our Ss were drawn is acknowledged with gratitude

This study explored the relationships between authoritarianism, work motivation, and occupational sex-role typing. There was a direct positive relationship between high F scores, extrinsic work motivation, and rigid occupational sex-role typing and between low F scores, intrinsic work motivation and flexible occupational sex-role typing. The way in which this directly affects men's perceptions about women at work is discussed. The study presented here explores a constellation of personality traits and attitudes related to authoritarianism and examines their contribution to a particular pattern of social and political perception.
