wish: Wish's Morse-code-like Data

Description

Wish's (1967) Morse-code-like data of discrimination probabilities among $32$ auditory Morse-code-like signals.

Usage

wish

Arguments

Format

The wish data frame consists of $32$ rows and $32$ columns, representing the Morse-code-like signals (see ‘Details’) presented first and second, respectively. Each number, a numeric, in the data frame gives the relative frequency of subjects who responded ‘different’ to the row signal followed by the column signal.

Details

The $32$ Morse-code-like signals in Wish's (1967) study were $5$-element sequences $T\_1P_\1T\_2P\_2T\_3$, where $T$ stands for a tone (short or long) and $P$ stands for a pause ($1$ or $3$ units long). As in Dzhafarov and Colonius (2006), the stimuli are labeled $A$, $B$, ..., $Z$, $0$, $1$, ..., $5$, in the order they are presented in Wish's (1967) article.

Wish's (1967) $32x32$ Morse-code-like data gives the same-different judgements of subjects in response to the $32x32$ auditorily presented pairs of codes.
