Effects of oral reading rate and inflection on intraverbal responding.

Tenenbaum et al. (1989) · The Analysis of verbal behavior 1989
★ The Verdict

Reading aloud at a high rate with inflection, approximating conversational speech, improved both the accuracy and speed of intraverbal responding (comprehension) more than any other combination of reading rate and inflection.

01Research in Context

01

What this study did

Six students read short passages out loud while the experimenter changed two things.

First, the kids read either very slow (40-60 words per minute) or fast (150-200 words per minute).

Second, they read either in a flat voice or with lively ups and downs like a storyteller.

After each reading the adult asked questions to see how much the child understood.

02

What they found

Fast reading plus lively inflection gave the biggest jump in correct answers.

Speed alone helped a little, but adding the storyteller voice doubled the gain.

All six kids showed the same pattern, so the effect looks solid.

03

How this fits with other research

Cortez et al. (2020) also boosted intraverbal answers, but they used Spanish picture cards instead of English stories.

Both studies show that how you present words changes later answers—rate and inflection here, tact versus listener training there.

Titlestad et al. (2019) surveyed teachers and found most ignore prosody when teaching comprehension; the 1989 data say that is a missed tool.

Rosenthal et al. (1980) warned that skills taught in one cue rarely jump to new cues; here the fast-plus-inflection mix worked for every passage, so the cue stayed constant while style changed.

04

Why it matters

Next time you run reading fluency drills, cue kids to read fast and with feeling, not just accurately.

One minute of modeling a bouncy voice can save ten minutes of re-teaching facts later.

05

Reading Comprehension as Intraverbal Behavior

From a behavior-analytic view, reading comprehension can be defined as a type of intraverbal responding: verbal stimuli in the text evoke related verbal responses, such as answering questions about what was read.

This study asked how the rate and inflection of oral reading affect that intraverbal responding. Four conditions were compared: low rate (40 to 60 words per minute) and high rate (150 to 200 words per minute), each with and without inflection.

06

Why Inflection Plus Rate Helped Most

The combination of a high oral reading rate with inflection, a condition that approximates natural conversational speech, produced the greatest gains in both accuracy and speed of comprehension responses. It outperformed every other combination of variables.

A second experiment replicated the finding across reading levels, passage content, settings, and subjects. Practically, this supports having learners read with expression at a fluent, conversational pace rather than slowly and flatly.

03Original abstract

Reading comprehension may be defined as a type of intraverbal responding. Only a few studies have reported the effects of the rate and inflection of oral reading performances on this class of intraverbals. In the present study the effects of four conditions; low reading rates (40 to 60 words per minute), with and without inflection, and high reading rates (150 to 200 words per minute), with and without inflection, were studied using six subjects. Two of the subjects were of high school age, reading below grade level, and four were typical third grade students, reading on grade level. The results indicated that the combination of high oral reading rate with inflection, a condition approximating conversational speech, increased both the accuracy and speed of intraverbal responding (comprehension), more than any other combination of variables. A second experiment was conducted which systematically replicated the findings across reading levels, reading passage content, settings, and subjects.
